Manchester United ace Wayne Rooney slaughtered Real Madrid defender Pepe on Twitter last night. Pepe was caught on camera allegedly stamping on the hand of Lionel Messi during Barcelona's 2-1 Copa win in Madrid.

A stunned Rooney tweeted: "Pepe. What an idiot. Sometimes people wind u up.

"Must be difficult to ref this game. Madrid v barca."

Then when Barca struck, Rooney added: "Haha. That goal serves pepe right."
