MANCHESTER, England (AP) -- Manchester United manager David Moyes says Wayne Rooney injured his hamstring before the club's preseason tour to Asia and Australia and dismissed suggestions the striker is set to leave the club.
Rooney returned home after only one day in Thailand and is expected to be out of action for a month, placing him in doubt for United's first match of the Premier League season against Swansea on Aug. 17.
"The day we left (Manchester for the tour) he just felt his hamstring tighten up right at the end of training and we thought there would be no problem,'' Moyes said. "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.
"We won't take any chances - there is no point in taking him any further round the world, so we've sent him back and he'll get treatment.''
Rooney wrote on his Facebook page: "Gutted to have picked up a niggling injury especially as training was going so well, heading back to Manchester to have it assessed fully but early indications are nothing to worry about.''
The early return provoked further speculation about Rooney's future.
Previous United manager Alex Ferguson revealed Rooney asked to leave the club at the end of last season, while Chelsea manager Jose Mourinho said Friday that the 27-year-old England international is a player he admires.
"People are entitled to talk about good players,'' Moyes said. "I am being asked plenty about Wayne, so I am sure Jose will be getting asked about lots of players as well.
"It is hard to keep repeating myself but I will do. Wayne is a Manchester United player and will remain that.''
