Whenever a big game like this comes around, you look to your captain for leadership and guidance.
Patrice Evra was disappointing for United. His usual forays down the left wing were restricted largely due to the great performance from Samir Nasri. When the two players inevitably came together, it was Nasri who came off best.
Evra showed his impatience when overstretching for tackles and committing needless fouls.
Vincent Kompany on the other hand will be the player who makes the headlines. The Belgian international rose highest just before half time to score the winning header that kept his club's championship dream alive.
The knock-on effect of Kompany's goal is yet to be understood, but it ought to do wonders for team morale at the training ground tomorrow.
Kompany was superb throughout and led by example.
