That's it from me this evening, but be sure to check out all the post-match reaction and analysis right here on Goal.com.
It's honours even here at the Stade Velodrome. Lyon miss the chance to go top of the table, while Marseille are now four matches without a Ligue 1 victory.
That's full-time! Marseille 1-1 Lyon!
Very late OL change. Pied comes on, Lisandro goes off.
OM have another corner, but Lloris rises high to gather the ball. Excellent from France's No.1.
Lloris punches the corner clear and we're into the three minutes of stoppage time.
Substitution Lisandro López Jérémy Pied
Oh... Good play from Andre Ayew! His shot is deflected wide of Diakhate. Corner!
There are huge gaps to be exploited, but neither team is coherent in the final third. Brandao slashes a slot past from the corner of the box.
It's a frantic end to the game at the Stade Velodrome, with both teams making cheap errors in possession. Both are going for the win though.
Brandao gets by Diakhate, who's having another uneasy night. Thankfully, centre-back partner Lovren clears. In the play that follows, Lucho scuffs a poor shot wide.
Kallstrom's kick is well cleared by the home team. Any slip now is likely to be costly.
More good play from Lyon, ending in a Cesar Delgado shot deflected just over the top. Corner.
Oh Marseille!!! Some clever headers around the box open up the Lyon defence, but Brandao slipped at the crucial moment as he appeared set to put OM ahead.
Substitution Michel Fernandes Bastos Jimmy Briand
Jimmy Briand comes on for Michel Bastos.
Surely a foul on Diakhate on Brandao. The Brazilian seemed to have spun in behind, but the referee doesn't think so! Play on!
Fanni gets a little lucky, missing his kick as Bastos drove a low cross into the box. His scuffed clearance drops to Mandanda.
Taiwo gets up and trots back onto the field. The referee shows no sympathy and gives him a yellow card.
Yellow Card Taye Taiwo
Ouch! Delgado and Taiwo clash near the touchline. The Nigerian, who actually fouled the OL man, is down and looks in some pain.
That's the former Toulouse man's last contribution. On comes Brandao.
Substitution André Pierre Gignac Brandao
GIGNAC! What a chance! A terrible back header from Diakhate lets Gignac in, but from a testing angle on the left, he lobs over Lloris and wide.
Gignac caught offside after Lucho tried to ping a first time pass to him following a poor Diakhate clearance.
Taiwo is getting forward well down the left, but on this occasion his foray comes to naught.
Substitution Bafetimbi Gomis César Fabián Delgado
Now Lyon are to make a change. Gomis walks off and is replaced by Cesar Delgado, who has been injured for much of this season and is just making his return.
Lucho has immediately been pushed forward into a No.10 role with that change.
Substitution Mathieu Valbuena Fabrice Abriel
Marseille are going to bring on Fabrice Abriel for Mathieu Valbuena, who's had a quiet game, aside from his goal, of course.
Kabore does well to check another surge from Lisandro. The forward keeps possession and has a strike from 25 yards out. Mandanda has no problems fielding the low shot.
Bastos! Half chance for OL! Lisandro delivered into the box from the left. OM weren't prepared at the back post, and though Gomis couldn't reach the ball, Bastos could. From a difficult angle, he shot over.
Lucho's corner is missed by Lloris, but it's too hard for any of his team-mates, letting OL off the hook.
Valbuena's tenacity draws an error from Reveillere, who gives away a corner.
Oh... Cheyrou tried to release Remy, but the pass was just too hard. Lloris gathers the ball with ease at the edge of his box.
Lyon's substitutes are warming up furiously. It may not be long before the first change.
Marseille seeing plenty of the ball, but they're struggling for penetration.
Gomis! Good chance for Lyon, but the striker placed a shot just by the post from a Makoun pass. Perhaps a quicker pass to Bastos would have been a better option for the African. The Brazilian was unmarked 18 yards out.
This game has seen several changes of momentum over the first hour. It's Marseille who are on top at present, but OL can't be discounted.
Remy! Half a chance for the former Lyon player, but he couldn't catch Taiwo's cross properly and the ball loops into Lloris' arms.
Again the set-piece from the home side is poor. Lovren heads clear, but his head knocks against Ayew's and he'll need some treatment.
The free kick is cleared with ease but Lyon's counter attack is countered again by Marseille. Gignac's cross is deflected over the bar by Lovren.
Diakhate fouls Gignac out on the left. This is a good position for OM. Cheyrou to deliver left-footed.
Lyon are really trying to put pressure on the Marseille ball carriers. The home players have little time in possession.
Claude Puel, the Lyon general manager, looks grim on the sidelines.
Oh... Good strike from Gonalons! From 25 yards, the holding midfielder caught his shot well, but Mandanda is firmly behind it.
It's not the Argentine's best. Lyon clear easily and Lloris gathers as OM attempt to cross once more.
Yellow Card Pape Diakhaté
Now the momentum is with Marseille! Lucho hovers over a free kick, positioned out on the left touchline, 25 yards out.
Suddenly OL have it all to do again! Cissokho makes another run down the flank, but this time his control lets him down.
OL respond by asking Yoann Gourcuff to warm up.
Assist Benoît Cheyrou
Goal Mathieu Valbuena
GOAL!!!! MATHIEU VALBUENA!!! Marseille level from nothing! Cheyrou tries a speculative shot from 20 yards, but Valbuena, like an ice hockey forward, just gets a slight deflection on the ball in front of Lloris, turning it into the net!
Yellow Card Charles Kaboré
What a dreadful free kick from Bastos! The Brazilian over-hits his centre, and it drops miles away from everyone.
Yellow card for Charles Kabore for a foul on Cissokho. The full-back is getting forward effectively and Lyon now have a free kick near the corner flag.
Cissokho burst down the left, but his cross is too hard for everyone in the centre. Good work from the left-back nevertheless.
Lyon pick up where they left off, keeping possession impressively. Marseille continue to go direct, but this is simply giving OL the ball back.
Marseille get the second half started.
There's no stoppage time, so it's half-time. A few whistles from the Stade Velodrome crowd. They're been silenced by a Lisandro strike 10 minutes before the break.
Lyon's defence has been poor so far this season, but it looks like they'll get to half-time still on course for their fifth clean sheet of the season.
Valbuena's had a quiet game so far. He tries a run down the right but is well checked. More frustration for 'Le Petit Velo'.
Marseille are making too many mistakes in the centre of the pitch. OL have had it fairly easy so far.
Mistake from Heinze, who lets Gomis turn and play a pass over the top to Bastos. The Brazilian had a decent chance to find the target from 20 yards, but his low drive flashes wide.
OM now struggling to get out of their half. In fact, the hosts are struggling to get a touch!
Lyon are well in charge now. Cissokho crosses into the box, narrowly missing Lisandro. Taiwo passes back to Mandanda, who slices his clearance badly. Lyon throw in an advanced area.
Makoun prods a pass to try and release Gomis. Fanni deals with the situation well. Marseille goal kick.
Michel Bastos gets away down the right again, but this time his cross is poor, going straight out.
All the noise in the Stade Velodrome is coming from a corner of the ground to the left. Unsurprisingly, that's where the OL fans are housed.
Assist Michel Fernandes Bastos
Goal Lisandro López
GOOOAAAALLLL!!!!! It's Lyon who have the lead! OL broke quickly down the right. A low cross into the box from Bastos was dummied by Makoun for the unmarked Lisandro, whose first touch was poor but whose second sent the ball high into the net.
Excellent hold-up play from Gomis, who couldn't quite get in behind Kabore from a Lisandro pass. The striker gets a shot in from 25 yards, but it's well over the top.
... His low, hard free kick is cleared at the first hurdle.
Play whistles on and OM win another free kick, again out on the right, but close to goal. Cheyrou again over it...
Oh... there's a little clash between Valbuena and Lovren. The referee ignores it, but the little winger gave the big Croat something of a rugby tackle.
Taiwo has another ambitious shot, this time from the corner of the box. It is blocked at source.
OM are playing in a more direct fashion than usual. The ball in behind is certainly causing Lyon problems, largely because of Remy's speed.
Oh... Lyon go close. It's Fanni who gets a good glancing head to a Gomis cross after the forward had got into a good position down the right channel.
It was total OM pressure for a period, but over the last couple of minutes Lyon have raided forward with a little more purpose.
More Marseille pressure! A high cross into the box from Remy is brilliantly controlled by Gignac, who cuts inside Diakhate and shoots towards the near post. His effort hits the side netting.
Lovely turn from Remy at the edge of the box, but he shoots over!
Remy's pace down the right is causing havoc. Lovren has trouble keeping up with him and does well to concede a corner in the end.
This one is headed clear but Lyon struggle to clear the danger until they're awarded a free kick.
Now the Velodrome crowd is in full voice, and OM are responding. Cheyrou eyes up a free kick in a similar position to the one just a second ago.
GOAL GIGNAC!!!!! NO OFFSIDE!!! Cheyrou's kick is delivered high into the box. It goes loose and Gignac shoots home at the far post. He wasn't offside, but Remy, who was in the centre had a prod at the ball, was!
Free kick chance to Marseille. This one is out on the right touchline, 40 yards out.
Lovely play from Lucho, who picks out Taiwo on the left. Though the first wave of the attack is quelled, Marseille won a loose ball on the edge of the box. Another cross comes in, but Cheyrou can't get any power in his acrobatic shot. Lloris easily saves.
Now it's Marseille's turn to have a spell of pressure. Gignac tries to get room down the left but his cross is blocked and goes straight to Lloris.
... but it's Taiwo who hits hit. The Nigerian has a great left foot but would have needed to do something remarkable to score from there! His shot is poor struck and cleared away by a defender.
Free kick to Marseille, very central about 40 yards out. Lucho's over it...
Oh... Remy gets in behind Cissokho for the first time and sends a low cross skimming across the box. It's too hard for Ayew, though.
This match is still to ignite. With quarter of an hour played, neither 'keeper has been tested.
A nice piece of triangular passing down the Lyon right threatens to undo the OM defence, but Gomis' pass to Reveillere is overhit. Goal kick to the hosts.
Marseille scramble a deep centre away in unconvincing style. Not a good start from the home side.
Gomis! First genuine moment of danger from OL! A clever pass from Bastos allows the former Saint-Etienne man to roll away from Fanni to strike at goal. From a tight angle, he shot into the side netting.
OL are starting to get a handle on things. It's the guests knocking the ball about more confidently.
Lyon have the ball in the net but it won't count! Gomis was punished for handball before he cut a pass back for Bastos to strike home.
Pretty horrible defending from Lyon. Lovren's clearance hits Diakhate and breaks kindly to Ayew on the edge of the box. Without time, he prods an effort goalwards but Lloris dives to his right to save.
Lisandro makes his first break of the game but steps on the ball, allowing it to go out of play. He'll play primarily down the left tonight, with Gomis through the centre.
Gignac's going to be hard for Lyon to police tonight. Already he's shown intent to drift out to the left and pose issues in the wide areas.
Lloris slides out onto a pass designed to meet the run of Remy. The former Lyon man can't reach Gignac's pass, coming up short by a yard or so.
There's still little pattern to this match. Too much possession is being given up in the centre of the field.
Gignac clatters into Reveillere, who made a big first minute challenge on Valbuena. No booking for the OM man.
Not much of an early pattern to this game. Lyon look like they'll try to disrupt the flow as often as possible.
Kallstrom has the first effort of the game, trying a left footed shot from fully 30 yards. Mandanda isn't tested.
It's Lyon, clad in their red coloured change strip, to kick us off.
And OL: Lloris (cap.) - Reveillere, Diakhate, Lovren, Cissokho - Makoun, Gonalons, Kallstrom - Bastos, Lisandro - Gomis
Here's the Marseille side: Mandanda - Kabore, Fanni, Heinze, Taiwo - Lucho, B. Cheyrou - Remy, Valbuena, A. Ayew - Gignac
When the sides met in their first encounter last season, a memorable 5-5 ensued. If there's half as much action tonight we're in for a treat!
Good evening and welcome to Marseille! We're round 10 minutes away from Ligue 1's showcase match of the weekend, pitting Olympique de Marseille against Olympique Lyonnais.
