Gordon Strachan unsure of Wayne Rooney's state of mind

Scotland boss Gordon Strachan has admitted that he is unsure whether England striker Wayne Rooney has been unsettled by speculation surrounding his future this summer.

The Manchester United forward has been widely linked with a move to Chelsea since the end of the season, while he is yet to turn out for David Moyes's side in pre-season.

However, despite a reported shoulder injury, the 27-year-old is expected to start when England welcome Scotland to Wembley on Wednesday.

"I don't know. You will have to ask him. I can't tell you how he is feeling," he told reporters at a press conference.

"I'm sure Wayne Rooney will appreciate it if I kept quiet as everyone else is talking about him. He is a terrific player and one of the best in the world."

Rooney has scored 36 goals in 83 games for England.
