The Slovenian goalkeeper appears slightly short of confidence at the moment and he looked particularly vulnerable from set-pieces. However, he did produce two fine saves to deny Kaka and Balotelli.
The Japanese was a constant threat with his tireless work rate down the left and although he often failed to choose the right option, he was at the heart of most Inter attacks.
Was burdened with the task of containing Balotelli and, on the whole, he did well, using his pace and strength to frustrate the Italy striker.
He is really starting to win over the fans after a difficult start to his Inter career and showed a good reading of the game to contain the Milan attack. A very encouraging display.
He offered support to the defence with his willingness to track back, although he did not show the full potential of his attacking capabilities.
Produced a number of key headers and interceptions to break up the Milan attack but looked rusty.
The evergreen Argentine was solid in his 47th Milan derby and his experience proved crucial to Inter's win.
He nearly opened the scoring with a speculative half-volley and he provided the assist for Palacio's winner with a low cross. Still frustratingly sloppy in possession at times, though.
The reliable Argentine turned in a determined and disciplined performance to break up the Milan attack and kept things tidy in the midfield with his accurate passing.
Was always willing to get forward to assist Palacio and create chances. He forced Abbiati into a smart save before being replaced late on.
The Argentine showed his class with a brilliant back-heeled finish to nick the win. His movement made him a constant threat to the Milan defence and was unlucky not to earn a penalty in the first half.
The Milan goalkeeper made several smart saves to deny Taider, Nagatomo and Palacio but could do nothing to prevent Inter's late winner.
Substituted at half-time due to an ankle injury but had been struggling up until then anyway.
He did not put a foot wrong in the defence and produced a number of well-timed tackles to frustrate the Inter attack. Unlucky to be on the losing side.
The Colombian centre-back was fortunate not to concede a penalty in the first half and despite marking Palacio excellently for the majority of the game, he was outclassed by the Argentine striker for Inter's winner.
M. De Sciglio
He showcased his potential with another promising performance down the right, joining in the attack on numerous occasions and preventing Nagatomo from getting crosses into the box.
The 22-year-old did not look out of place on his first league start for the club, demonstrating a good range of passing and a number of neat touches. However, he did not do enough, overall.
A desperately lacklustre performance from the stand-in captain, who struggled to show his ability and create chances for his team-mates.
N. de Jong
Offered good protection to the Milan back four and broke up a number of opposition attacks with his tenacity and strong tackling.
An energetic performance from the Ghana international, who kept things tidy in the centre of the pitch. However, he was a red card waiting to happen and was sent off for pushing Kuzmanovic to the floor.
Missed a glorious chance when he blazed over from close range, which pretty much summed up his evening.
He failed to find the net against his former club and although he showed glimpses of magic, he was kept very quiet by the Inter defence for the majority of the game.
