Chelsea legend Petr Cech believes Chelsea goalkeeper Djordje Petrovic should have done more to prevent Crystal Palace taking the lead in Monday’s clash at Selhurst Park.

Crystal Palace took the lead in the first-half after Jefferson Lerma unleashed an absolute screamer from distance before the Blues scored three goals in the second-half to win the game 3-1.

“Petrovic drops to the goalline to have a little bit more time to step and push,” Cech told Sky Sports.

“But you can step up, gain a yard and close the angle. He had a very good step and push but couldn’t get there.

“Personally, I would be higher and have a better chance. I think a small touch would have been enough.”
