Wayne Rooney has told Manchester United fans to expect big things from Dimitar Berbatov this season.

"You can see in training and games during pre-season Dimitar has looked sharper," he said.

"He looks like he is more determined.

"He is tracking back with the full-backs in pre-season and is definitely working harder and trying to impress.

"He is a brilliant player. He has so much quality he has got and we all want him to show it."
