Unsettled striker Wayne Rooney refused to discuss his future at Manchester United in his first public comments since he was linked with a move to Chelsea.
The 27-year-old made his first appearance for United this season as a substitute in their 4-1 win at Swansea City on Saturday, laying on second-half goals for Robin van Persie and Danny Welbeck.
However, a picture that was circulated widely on Twitter showed that he did not celebrate with his team-mates after Van Persie's goal put United 3-0 up, fuelling speculation he remains concerned about his Old Trafford future.
United have rejected two bids for Rooney from Chelsea during the close season, but he was reluctant to comment on their approaches.
Quizzed about his future by Sunday newspaper reporters after England's 3-2 friendly win over Scotland on Wednesday, he said: "I am here to talk about England."
Rooney missed United's entire pre-season campaign with hamstring and shoulder injuries but played for the first 66 minutes against Scotland before his second-half cameo at Swansea.
He admitted that he needs to get more playing time behind him in order to return to top form.
"You are always looking forward to a good pre-season," Rooney said.
"It's important you do that, but I had the injury to my hamstring and the injury to my shoulder so it's disappointing.
"But I've had to deal with it and I have been working hard to try to get myself fit again.
"I've missed pre-season with a couple of injuries but I played a few minutes (against Scotland) and hopefully I can kick on now."
