Chelsea midfield ace Frank Lampard says the enthusiasm of Manchester United striker Wayne Rooney inspires the entire England squad.

Lampard has no doubts Rooney will catch form by the time the World Cup kicks off.

The England midfielder told Match of the Day magazine: "Wayne Rooney is full of energy and not just on the pitch.

"Some players go back to their rooms and watch films all day, but Rooney is never in his room!

"He's always bouncing around chatting to people, having his bit of fun. I'm sure he's desperate to get out there. He'll talk about anything.

"He loves talking about football but he'll talk about anything and everything. You need people like that in the camp because it's not easy being stuck in a hotel all day.

"He's the main character - you can always hear his voice."
