De Bruyne goes for goal with a long-range free kick, but Courtois is never going to be beaten from there.

MF Raheem Sterling 8 - Happy to run at the heart of the Chelsea defence, he drew a string of first-half free kicks in risky positions.

Chelsea: Hazard, Alonso, Fabregas, Kante, Morata, Pedro and Cahill.
