"Regular game time is really important to me, it has been throughout all my career," he said. "The actual opportunity to go to West Ham wasn’t really agreed between both clubs and myself, so it wasn’t just my chance to say ‘yes’ and I’m doing.
"The actual opportunity wasn’t there because we didn’t get far enough down the line with it. West Ham are a massive club, my focus is still on Manchester United. I want to fight for my place, but, of course, game time is really important to me."
