Manchester United manager David Moyes is a worried man after the clubs star striker had to leave the game during a pre-season friendly against Yokohama in Japan.

Moyes revealed that Chelsea target Wayne Rooney’s hamstring injury has responded well to treatment and the 27-year-old might be fit enough to join up with the club in Stockholm for their August 6th friendly

‘We’ve got a couple of wee worries,’ said Moyes. The main worry of course would be seeing the Dutch international sidelined for a lengthy period which would be a serious blow for United as they try to defend their title.

‘Robin just felt his thigh in the first half and we didn’t want to take any chances.

‘Danny Welbeck also felt his groin when he went on and we’ve just got to make sure they’re all OK, especially with so many games coming up.

‘We’ve still got a few games to play before the season starts when we get back home.

‘As far as we know, Wayne is coming on. He’s started light jogging and the feedback I’m getting from the physios is that he’s progressing. Hopefully those dates are still on track.

United lost the match to Yokohama 3-2 and now move on to Osaka for the next match of their tour.
