The veteran German could do nothing about the goals and, though he looked shaky with a few early clearances, the goalkeeper did nothing particularly wrong.
The right back enjoyed himself in the first half, causing Chelsea's left flank problems, but never really capitalised on the crossing opportunities afforded to him.
Marshalled the Schalke defence adeptly for the majority of the night, though that all went to pot once they conceded the second goal.
Was defensively strong for the most part, though he did go missing for the second goal and proved helpless for the third.
Was very disappointing as he found himself in an unfamiliar striking role that clearly did not suit either him or his team.
The midfielder played well, particularly in the first half, picking out some nice passes, though he will be disappointed with his part played in the opener as he was caught ball-watching for Torres' goal.
Showed some nice touches but was largely a passenger in tonight's contest, failing to provide any penetration for the home side.
Had very little effect on proceedings, barely featuring for the home side and giving away the ball for the second goal.
Sat in front of the back four quite well, though flailing helplessly against Oscar for the second might be his resounding memory of the night.
The midfielder was Schalke's great hope coming into this game and he failed to deliver as, a few nice touches aside, he was largely ineffectual.
Was probably, and unexpectedly, Schalke's best performer of the night as he got forward down the left and put in some excellent deliveries.
Made a few smart saves in the first half but was never particularly tested. Did everything that was asked of him, however, and can be happy with his performance.
The veteran centre-back has come into form in recent weeks and that continued here; he nullified any threat that Schalke, and Boateng in particular, posed with characteristic poise.
Provided Torres with the opener with a thumping header at a corner and though he struggled to contain Aogo in the first half he was solid for the most part.
Starting in an unfamiliar left back berth, the right back visibly struggled against Uchida in the first half, though he improved notably in the second, forming part of an extremely impressive Chelsea defence.
Started in place of David Luiz, presumably with the hope of instilling some defensive stability, and he duly repaid his manager's faith with an extremely solid performance.
Provided Hazard with a lovely pass for the third and was a constant presence in midfield, buzzing around the Schalke midfielders and generally making himself a nuisance.
Although fairly quiet for most of the game, the Belgian came alive for the last two goals, countering at some speed to provide his side with the goals that killed off the contest.
The Chelsea veteran, as is often the case these days, was a quiet but influential presence, retaining possession well and providing the Blues with some presence in the middle of the park.
Provided a lovely assist for Torres' second and, though quiet in an attacking sense for the rest of the game, kept his shape well and did what was asked of him - which Mourinho values so highly.
Came in for Samuel Eto'o and duly grabbed his goals. The Spaniard looked lively all night and helped create Hazard's goal with a smart run off the ball.
The German's inclusion over Mata still raises some eyebrows in some quarters but he was Chelsea's most threatening attacking force in the first half and impressed intermittently throughout.
