Into stoppage time now, two minutes to be added.
RONALDO!!!?!?!?! INCREDIBLE MISS!!! In front of goal he unselfishly fed it wide to Higuain and the Argentine passed it back across the six yard box and Ronaldo somehow failed to tap-in from close range. Higuain got another bit at the cherry to but drove it wide. Madrid must have had close to 40 shots at goal tonight.
Substitution Mesut Özil Canales

Great interchange from Higuain and Ronaldo gives the Argentinian a shot at his hat-trick inside the box but yet again he fires wide.
Surely the insurance goal from Madrid, 2-0 up should be game over. Will they look to score more goals? Will Jose dare to entertain? Can Ajax find a way back into the game?
GOOOOOAAAAAAAAAAAALLLLLLLLLL!!!! Higuain with a 2 yard tap-in. Oezil took a brilliant save out of Stekelenburg after latching onto di Maria's flick over the Ajax backline but the rebound fell to Oezil who squared to to the Argentinian, who simply couldn't miss from there.
Goal Gonzalo Higuaín
The pace of attack from Madrid has waned a little in the last few minutes but they are still in total control.
Substitution Demy de Zeeuw Teemu Tainio
RONALDO! Flashes a shot about a foot wide of Stekelenburg's left hand upright. Straight in front of goal 18 yards out he should have done better.
di Maria lofts a delightful ball over the top to Higuain in acres of space, he's incorrectly flagged offside. Great control from the Argentine but denied this time by a poor decision.
It's rolled to Alderweireld who drags his effort wide of Casillas' goal, no danger to Madrid's tender lead there.

Higuain tries to turn and find space in the box but Ajax manage to clear it.

Higuain with neat control and a volley high over the crossbar.
Madrid immediately on the front foot, Higuain wins a corner after seeing his shot deflected but he had Oezil and di Maria in support and maybe should have played one of them in.
Ajax get the second half started and on the first half performance have a lot of work to do in this period.
Ajax may feel they are still in this and may be able to sneak a result but they will have to commit more in attack after the break which will inevitably leave holes for the hosts to expoit. It should be an interesting second half.
To describe the first half as one-way traffic would be an understatement. Madrid have been utterly dominant but they can't be happy with their efforts on goal. They haven't really carved out many clear openings and have been largely restricted to shots from distance. When they have got in, the finishing has been quite poor and they had to rely on a set piece for their only goal so far.

Alderweireld concedes a corner with a challenge on Oezil inside the box but Stekelenburg is on hand to punch clear from the corner.

Ronaldo fires one at Stekelenburg from 20 yards but he gets down to save with relative ease. He's having a busy night between the sticks.

Ajax corner comes to nothing and Madrid are back in control of the contest.
Marcelo is in!! Onto Ronaldo's excellent through ball but opts to square it to Higuain from 8 yards!?! The Argentinaina scuffs it and it falls to di Maria behind him but he blazes over. It should be 2-0. WHAT A MISS!!!
GOOOAAAAAAAAALLLLL!!!! Gonzalo Higuain from an Alonso corner! He didn't know much about it, a slight touch off his head at the near post with Ricardo Carvalho helping him with a gentle nudge in the back.
Own Goal Vurnon Anita
Brief respite for the Dutch who now resume defensive duties as Alderweireld hoofs a long ball out of defence.

Clever run from Oezil down the right, gets along the byline and tries to drill a low ball across the box but Stekelenburg gets down smartly to save.
Ajax are without Uruguayan striker Luis Suarez of course but Belgian stopper Jan Vertonghen is also absent.
Demy de Zeeuw with a hefty chalenge on Marcelo on the near touchline, gives possession back to Madrid.
Yellow Card Demy de Zeeuw
Neat layoff from Mesut Oezil to countryman Sami Khedira who has mMadrid's first strike on target but it's straight at Martin Stekelenburg.
Alonso finds Higuain on the left and he skips past the defender to the byline before angling a ball back for Angel di Maria who failed to get a significant touch and only managed to direct it wide.
