It's unusual to see a goalkeeper concede five and end up relatively blameless, but Julio Cesar wasn't fully complicit in this defeat. He couldn't have done much about the goals.
A mess, a shadow of his former self. The formerly world class right-back did little going forward and cheaply gave the ball away. But it was at the back where he was found out; he left far too much space.
Two red cards in four days and another dreadful performance from Chivu. Let Raul wander past him for an easy chance before leaving the pitch. At least when he was sent off he could do no further damage.
A tale of two halves. In the first period he was OK. In the latter 45... well, it's safe to say that if he wasn't the worst defender on the pitch, it's only because his central partner was sent off. A truly artless second half performance.
In the first period Zanetti was among the best of the bunch, putting in an aggressive but controlled shift. In the second half he uncharacteristically sank along with his team-mates.
Decent in the build-up as Inter came forward in the first period, but he, like so many others, absolutely disappeared in the second half.
A rare bright spot in the Inter ranks; the 30-year-old was excellent in anticipation and always found himself in the right areas. A prime example is his header to set up Milito's goal.
Much like the rest of the midfield, his skill and technical proficiency gave way to a game of hide and seek in a poor second period.
A wonderful, wonderful goal - one to remember forever - was his sole contribution on an injury-hit night, but one that at least sees him leave with his head held high.
Put in some superb moves in the first period but also passed up chances, including one that could have given the Nerazzurri the lead early in the second period.
Involved in some neat moves and also continued to battle hard in the second half even when all was lost.
Maybe he could have cleared to the side before Stankovic's great goal, but it's hard to fault him. Dealt very well with Eto'o after the break - another good day at the office.
Despite a superb recovery in the second session, where he grew along with his team's scoreline, a difficult first half showing means that he must be marked down.
The best of a bad defensive bunch across the two teams, but that is to be damned with faint praise.
It was his positional error that gave Inter their second goal. Surplus to requirements in the second period.
Uchida looked very active going forward and was a good influence in the second period, but his toils against Milito in the first half blot his copybook.
The midfielder-cum-centre-back was Schalke's poorest performer, and lacked composure on a difficult evening. Yes, he scored, but otherwise this wasn't a good evening for Matip.
Looked a little lost at times but grew into his role as the match progressed.
Schalke's surprise package. His distribution was good, his action on the ball was fine, and he also didn't squander possession. Very impressive.
Recovered from his early errors to put in a fine second half showing, including an assist for Raul. Will miss the second leg, but it hardly seems to matter now.
Like all great strikers, he is able to follow up 45 minutes of absolute anonymity with a true forward's goal. That's why he remains valuable even at his age.
Yes, you read it right: Edu was the top performer at San Siro. A tremendously committed and brave performance saw him net twice in an evening that he'll be dining out on for years.

Had little opportunity to change much about a game that was already becoming a lost cause.
There was little he could do, and he did it, as it were. Not a performance to remember.

Lasted barely half the game before being sacrificed - a substituted substitute.
