20:26 This concludes our live build-up for this evening. Now you can head over to our live match page to get ready for the big match. This is Ewan Macdonald signing off - be sure to join us for LIVE text commentary of Chelsea-Barcelona!
20:17 Now some analysis from Goal.com's Stephen Crawford: "I think it's too tough to call. Barca are extremely hard to beat on home soil, but with their 4-3-3 setup, I think they'll be caused problems in the midfield, the Blues operate well in the middle of the park. And, if Chelsea play with two holding midfielders, it'll be tough for Xavi and company to find a way through. As we all know, though, Barca can score from anywhere, and on a small side note, expect to see Bosingwa in the ref's book at least once - he'll crumble under all the Messi pressure. Prediction: 2-2."
20:10 My own prediction - my being Goal.com's Ewan Macdonald - is that Barcelona are going to edge it 2-1 as well. Prior to seeing the line-ups I would have said 2-0, but Chelsea, I feel, have enough about them to manage that priceless away goal.
20:00 I've put my Goal.com colleague, Sulmaan Ahmad, on the spot by asking him for his prediction. He says, "In light of the midfield battle we're now looking at, this game will be full of untold amounts of pressure. It will be hard to see how even Barcelona will be able to break through that many players. Chelsea don't have much firepower on display, but counterattacks will be the order of the day and anything can happen. They could nick one. Barcelona will not have it easy tonight; 1-1 or 2-1 in their favour being the most likely results, and if pressed I would have to go for the Barcelona win, because goals can come from so many different areas of that team. 2-1."
19:51 Well, Guus Hiddink and Pep Guardiola have gone all-in with these line-ups. The cards are well and truly face-up, so it's time now for the turn and river. Who will win this particular bet? You'll find out LIVE on Goal.com as we start match commentary prior to kick-off this evening. Stick with us for a bit more analysis, though, prior to kick-off.
19:45 CONFIRMED CHELSEA LINE-UP: Cech; Ivanovic, Terry, Alex, Bosingwa; Ballack, Mikel; Essien, Lampard, Malouda; Drogba.
Expert opinion from Goal.com's Sulmaan Ahmad: It's a slightly strange but ultimately perhaps sensible line-up from Hiddink, we will have to see exactly how it lines up. Initially, you get the impression it's a diamond midfield, with Mikel sitting deep, Essien and Ballack box-to-box and Lampard at the head, with Malouda and Drogba up front. But we all know Malouda is far from a striker. It looks more likely that Michael Essien will be deployed in a right-wing sort of position, maybe doubling up to deal with the threat of Iniesta, that will mostly come from the left. Malouda will do likewise, assisting Bosingwa to neutralise Messi. Factor in Mikel and Lampard in a direct dual with Yaya and Xavi and you have one hell of a battle. Guus knows what he has to do to beat Barca, and that's to crowd out the midfield. The only thing he may regret is being unable to counterattack down the wings and get good crosses into the box for Drogba to finish off.
19:44 CONFIRMED BARCELONA LINE-UP: Victor Valdes; Daniel Alves, Pique, Marquez, Abidal; Xavi, Toure, Iniesta; Messi, Eto'o, Henry.
Expert opinion from Goal.com's James Walker-Roberts: Big surprise from Pep Guardiola as Carles Puyol is only on the bench and Rafa Marquez and Gerard Pique start in the centre of defence. The Spaniard is one booking off suspension and may have a knock so it's unlikely to be a purely tactical move, bearing in mind the strength and power of Didier Drogba. Elsewhere, no surprises in midfield or up front as Barcelona go with an attacking formation that will see Yaya Toure battle against the likes of Michael Essien whilst Xavi and Andres Iniesta try to create chances for the front men. But Chelsea are looking to overload the midfield - can the Blaugrana cope?
19:41 The last Barcelona player to score against Chelsea, meanwhile, was Eidur Gudjohnsen, who struck early in the second half of that game. He's unlikely to start tonight, of course, but we'll confirm the lineups for you very shortly...
19:35 Remember: the very last goal scored between these sides was in that 2-2 Camp Nou draw. Didier Drogba netted right at the very end. Can history repeat?
19:27 We're expecting the confirmed line-ups within fifteen minutes. As a reader, Assaad from Lebanon, points out, Chelsea kept the cameras away from their final training session: what does Guus Hiddink have up his sleeve?
19:20 Frank in Liverpool asks, "Who will grab the headlines tomorrow?" For me, Andres Iniesta has what it takes to provide cutting edge. As for whether or not Lionel Messi can excel, that's 50/50. I expect this to be a very midfield-based game and as such we can maybe consider seeing Frank Lampard's name in the papers, too.
19:15 For those who believe that weather could play a part, it's nice and warm in Catalunya at the moment - a bit under 21 C (70 F), which is mild for the time of day. Although it's clouding over a bit now, it shouldn't rain this evening.
19:10 There are two players in the Chelsea squad who signed straight from Barcelona, namely Deco and Juliano Belletti. Another, Ricardo Quaresma, took a more circuitous route to get to Stamford Bridge.
19:07 A little bit more trivia. Players in the Barcelona squad who have played for Chelsea in the past are: Eidur Gudjohnsen... that's it! But others have played in England: Thierry Henry, Sylvinho, and Alexander Hleb have all lined up in the Premier League for Arsenal.
19:04 Here's a comment from Nicky in Malta: "Barcelona are favourites, but Hiddink knows exactly what he's doing. The only time Barcelona falter is when they realise their opponents are not running scared & will actually challenge them. For that reason Anelka will start, not Kalou." That's a controversial opinion - we'll find out soon if it's right!
19:01 In around forty minutes we should have the confirmed line-ups.
18:53 Chelsea fans have traveled to Barcelona in considerable numbers. They've come a long way since they were scrambling around in the old Second Division. Twenty five years ago today they won promotion to the top flight. Now look at them!
18:46 Chelsea have Ashley Cole already suspended, of course, but they only have one player one booking away from sanction. That's Nicolas Anelka, who seems unlikely to start in any case.
18:44 Rob from Estonia raises an interesting point regarding the FCB defence: "I think Puyol will be on bench today, because both, him and Alves are one card away from suspension and losing both for the rematch in Stamford Bridge would be a huge blow. If Alves gets booked, Barca can replace him with Puyol for the rematch against Chelsea. Also El Clasico is looming, so Blaugrana need Puyol fresh and rested. So I think Pep will put out Alves-Marquez-Pique-Abidal tonight..."
18:41 A lot of readers are saying that Yaya Toure will edge Seydou Keita out in the line-up for Barcelona. This indeed does seem to be the case. Remember, we'll have the confirmed line-ups for you the minute they're announced - probably in an hour or so.
18:35 An article commenter named 'Build it up' has submitted the following curious fact: "Chelsea manager Guus Hiddink coached Valencia (1991-93), Madrid (1998/99) and Betis (2000). He beat Barça twice in the League, drew once and lost six times. He’s lost on all four previous visits to Camp Nou and always let in three goals."
18:30 Since 2004 there have been two wins, two losses, and two draws for each side in the Champions League. Going back further, though, one finds a stunning 6-4 aggregate win - including a 5-1 victory at Camp Nou - for the Blaugrana back in 2000. Way, way back in 1966, Barcelona and Chelsea fought out a 2-2 aggregate stalemate before the Blaugrana won 5-0 in the third match.
18:23 The answer to the trivia question - who scored the first goal the last time Chelsea met Barcelona - is none other than Deco, who netted 3 minutes into the 2-2 draw between the sides at Camp Nou in the 2006-07 group stage.
18:18 Here's a trivia question to get you started. Who scored the first goal the last time Chelsea met Barcelona?
18:14 As always, be sure to keep your reader comments cming in at the foot of the page. We'll highlight some of them in the build-up, and I'll also be asking a few trivia questions. (Not for prizes - just for fun. If you want prizes, head over to Goal.com Manager, our online fantasy game!)
18:09 Then there's our predicted Chelsea line-up of: Cech – Ivanovic, Alex, Terry, Bosingwa – Essien, Ballack – Kalou, Lampard, Malouda – Drogba. Will it be correct? We'll find out in just over an hour with the confirmed line-ups.
18:06 Let's start off by taking a look at our Goal.com predicted line-ups. Match previewer KS Leong sees Barcelona lining up like this: Victor Valdes – Dani Alves, Puyol, Pique, Abidal – Xavi, Keita, Iniesta – Messi, Eto’o, Henry.
