Juventus defender Andrea Barzagli admits Italy have big concerns over England striker Wayne Rooney.
The Manchester United ace is sure to start against Italy tonight in their World Cup opener.
Barzagli said: "Rooney is an international player with great experience and quality, but England have three or four important forwards. They are fast, young and strong in the one-on-one.
"Rooney is an outstanding forward, always dangerous. England certainly have a strong front line and we will have to be wary of that."
