Untested in the first half - though he was fortunate Draxler and Szalai screwed wide with early efforts - but made an excellent stop to deny Draxler an equaliser early in the second half.
Fuchs gave him little to worry about defensively, but he lacks the technique and crossing ability to do consistent damage going forward. Schalke often left him open and never regretted it.
The Chelsea captain marshalled his defence with typical calm and, beyond the first 20 minutes, Szalai caused him few problems.
Draxler tormented him at times but he grew in confidence as the night wore on and looked markedly more comfortable after the boy wonder was withdrawn.
Good on the ball and dominant in the air, he overcame some early wobbles to give an assured display.
Worked hard - he always does - but could not find a way to create anything of significance up against Matip and Neustadter.
Not afforded as many opportunities to hare from box to box, he nevertheless hassled and harried well.
Did nothing until he beat Fuchs to the ball and fed Eto'o for the Cameroonian's second. Still looks far more effective when he has space to run into.
J. Obi Mikel
Used the ball economically and intelligently, calming Chelsea in their more panicky moments.
Forced a top save from Hildebrand early on with a wonderful Gareth Bale-esque free kick, but found it harder to influence proceedings from open play. Cuts inside too much on the left, and not to as deadly effect as Hazard.
Was the only man in the ground who realised how complacent Hildebrand was over his kicking and took full advantage to give his side the lead against the run of play. His second was far more typical Eto'o - a nerveless clip into the bottom corner from just inside the penalty area.
Made an excellent save from Schurrle's free kick early on, but undid all of his side's good work by dallying over a kick and allowing Eto'o to get too close to him. Could do nothing about the second or third, but the damage was already done.
Defended solidly in the air and on the floor, and was not directly responsible for either of the first two goals, though he was too static for the third.
Showed good strength, technique and composure to keep Eto'o as quiet as he could. Unfortunately for him, it was not quiet enough.
Always looked a square peg in a round hole on the left flank, and made a decisive error when he sold himself against Willian in the build-up to Eto'o's second.
Got forward well from right-back in the opening stages, but found himself pinned back against Schurrle as the evening wore on.
Gradually found himself outworked and out-passed by Ramires and Mikel, and was eventually reduced to several cynical fouls to stop promising counter-attacks.
The most dangerous man on the pitch - whenever his side could get the ball to him. Narrowly missed with a low shot early on and had Cech at full stretch at the start of the second half. Appeared to pick up a knock and was replaced by Clemens just after the hour mark.
Looked menacing in Schalke's opening rally, but faded and was withdrawn with 10 minutes left.
Very neat and tidy in the midfield, but could not prevent Chelsea gradually tightening their grip on the possession battle.
Dealt well with Willian, and Ivanovic gave him few problems. Not the attacking threat he was at the Veltins Arena, though.
Spurned a decent chance early and that was all he got to work with. Shackled well by Cahill and Terry.
