Manchester United boss David Moyes has revealed that Wayne Rooney is still struggling with a groin injury and may miss further matches. The England striker was a doubt for the Premier League game against Tottenham on Wednesday after missing the 1-0 win at Norwich City on Saturday. Rooney came through the 2-1 defeat against Tottenham at Old Trafford on New Year's Day, but Moyes will take a cautious approach with his leading scorer to prevent exaggerating the injury. Moyes said: "The plan was to play Wayne for 90 minutes (against Tottenham), but he has a bit of a groin injury. "The longer it went on, we had to try to get more attacking players on the pitch to try and find more ways to score. If I could (rest Rooney) I would, but the games are coming thick and fast.
