Showed excellent agility to make saves whenever he was called upon, though his positioning and decision-making were a little suspect. Could do little about either goal.
Recycled possession well, but didn't always look comfortable with the high line his team had committed to, earning a booking for cynically fouling Oscar in the first half.
Must have thanked his lucky stars when Hazard pulled up against Aston Villa on Saturday, as Chelsea possess no one else who could run at him with such skill and conviction.
Dominant in the air against Torres, but his lack of pace was starkly exposed by the Spaniard as Chelsea took the lead.
His pace and determination gave Cole problems, and his incisive passing created some of Benfica's best chances. Wasteful in front of goal though.
Used the ball economically and tidily to keep the likes of Gaitan and Salvio well serviced, and rarely gave the ball away. An impressive performance against his former club.
His energy and pace were crucial to Benfica winning the midfield battle, and he repeatedly committed opponents with surging runs through the middle.
Rarely troubled defensively and helped the Benfica midfield smother Chelsea for the first hour.
Showcased his superb close control to consistently escape the attentions of numerous Chelsea defenders. It's just a shame he left his shooting boots at home.
Proved a handful up front in spite of his lack of pace, linking well with Benfica's creators and, when his moment came from the penalty spot, he took it nervelessly.
His usual, unflappable self, commanding his area superbly and making saves whenever required. Could do little about Cardozo's drilled penalty.
Never shirked a challenge in the air or on the floor and marshalled the backline well in the absence of Terry. Made a crucial tackle in the dying moments.
There were occasional reminders of his technical limitations, but he defended stoutly in the face of what at times resembled a siege. Came up trumps with a priceless, towering header in injury time to win it.
His battle with Salvio was one of the most compelling on the field, and one he didn't entirely win. That said, he didn't disgrace himself either.
A mixed bag. Some very good, incisive passes and crucial interceptions, but also some wild decisions which unnecessarily ceded possession to Benfica.
Generally stood up well to Gaitan, but a strange decision to stick his arm out in the penalty area marred an otherwise perfectly good display.
Starved of the ball in positions where he could hurt Benfica, but his touch and balance were uncharacteristically too poor to make the most of the few opportunities he had.
Another less than convincing performance after Saturday's foolish dismissal against Aston Villa. Didn't offer Azpilicueta much protection and his touch let him down too often going forward. His pace was a constant threat to a high Benfica line though.
Used the ball sensibly on the relatively few occasions he got it and almost opened the scoring with a shot Artur misjudged. So unlucky not to score with a 30-yard screamer which struck the bar.
Not at his brilliant best. Seemed to struggle with the pitch and missed having Hazard to link up with, but still played the odd dangerous pass. Put in the corner for the winner.
Relatively anonymous until he pounced on a high ball from Cech, held off Luisao, rounded Artur and slid in the opener. Seemed to fancy it thereafter, but his decision-making and execution was still baffling at times.
