Nearly caught out when a rash decision to clear well off his line saw him almost lobbed by Willian. Saved from Torres early in the second half.
Struggled to close down the space in front of Torres, and did not last past the half time break, being swapped for Kaya.
Had a few wobbles at the back, but came up trumps at the other end, stabbing home Sneijder's corner to give his side a vital lifeline for the second leg.
Not quite as defensively suspect as Eboue on the opposite flank, but he still was careless, and left a few gaps in behind. Tested Cech with a long range drive.
He endeavored to push high up the pitch, but could not get much going in attack. To make matters worse, he was caught out of position regularly, not least for Torres' opener.
Gave the ball away a number of times, but won his fair share of free kicks in the second half, and improved admirably to break up the opposition's play.
The winger missed the target with two shots and failed to provide the defence with any sort of protection before his early withdrawal in the first half.
Largely a non factor in the first half, but his distribution improved after the interval, particularly his dead ball deliveries. One such ball set up Chedjoiu's equaliser.
Came within inches of converting a golden chance, as he attacked Drogba's flick on but succeeded only in hitting the post.
Won a few headers, particularly one that set up Selcuk's second half chance. A good target for the home side, but he suffered from a lack of support.
Moved well down the left flank at times, and escaped the attentions of the opposition defence more than cone. But the profligacy of his teammates and hos own inability to deliver the final ball meant that his efforts were in vain.
Could have shown more authority off his line to get to the ball ahead of Chedjou, though he was clearly expecting Terry to deal with the ball. Tipped away a Telles stinger late on.
Locked down matters on his side of the field, ensuring that Gala had no avenues forward. Did not often look to get forward, but that was never in his plans.
Caught out twice in the second half by high balls, and one lapse proved costly as Sneijder's corner sailed over his head, allowing Chedjou to stab home Gala's leveler.
Found a few opportunities to overlap down the left hand side, and one such run brought the opening goal of the game as he broke free and squared for Torres to score.
Went about his business at the back quietly and effectively, and it was hard to find fault in his display today.
Did not add much in an attacking sense for his side, but was solid patrolling in front of the back four. Another who executed his job.
Put in an admirable defensive shift, winning the ball back a number of times. Almost scored himself when he tried to lob Muslera following a mistake.
Somewhat conservative given his heights of recent weeks, but stuck to his task, not neglecting his defensive duties.
Solid when covering the back four off the ball, and came up with a few raking passes forward. Not the most expressive game, but a disciplined and cool-headed display.
His pace and willingness to move off the ball towards the touchline ensured that play was always stretched when Chelsea looked to break. Not often the most involved though.
Worked very hard up front and was aided by lax marking from the opposition defence. Arrived at the right time to stroke home Azpilicueta's cutback to give Chelsea a early lead.
