LONDON (Reuters) - Manchester United manager David Moyes said there was no point in risking Wayne Rooney on the team's Asian tour, which is why the injured striker was returning home just hours after arriving in Bangkok.

"We won't take any chances, there is no point in taking him any further around the world," Moyes told MUTV from the Thai capital, explaining that Rooney suffered the injury before leaving England.

"The day we left, he just felt his hamstring tighten up right at the end of training and we thought there would be no problem," the Scot added. "But after the long flight, we decided we'd get him tested and scanned and have a look at things and there is just a small grade-one injury there."

The 27-year-old faces a month on the sidelines after suffering the injury and is doubtful for the Community Shield against FA Cup winners Wigan Athletic at Wembley on Aug 11 and England's friendly against Scotland three days later.
