Rooney will have point to prove against Man Utd, says Solskjaer

Ole Gunnar Solskjaer believes Manchester United great Wayne Rooney will be a threat in Thursday's FA Cup clash against Championship side Derby.

Rooney, United and England's all-time top scorer, will line up against the club where he enjoyed so much success when lining up for the Rams at Pride Park.

Rooney joined the second-tier side as player-coach after a stint in the United States with DC United and former team-mate Solskjaer is wary of the 34-year-old's threat in the fifth-round clash.

"He gave absolutely everything for this club and we all appreciate that," the Norwegian manager said.

"But any goal he scores against us will be chalked off his goal tally. He doesn't want to score too many of them.

"He's a threat, in and around the box, set plays, and of course this game Wayne will show what he can do and he wants to prove that there's still fight in an old dog.

"We've got to be on our toes, don't give him any space in and around the box or in midfield."
