Chelsea goalkeeper Petr Cech goes into their clash with Manchester United having studied up on Wayne Rooney.

Cech admits he will spend long hours studying Rooney's goals.

He said: "Every time I play I watch videos of opposition goals. I've been doing it all my career and the only difference this time is the video will be a bit longer than normal!

"You can see there are ­similarities in the movement when he scores. The main ­target is to see everybody's movement - so you know when the cross is coming where people should be.

It gives you an extra second and you can deal with it. That's the reason I study it."
