After United twice rejected offers from Stamford Bridge, he has started the new season with a bang.
“I don’t think there was that much that went on,” Charlton told the Manchester Evening News. “I was never pulled into a situation where I had to decide what do we do about Wayne Rooney.
“I don’t know whether someone said the wrong thing or caught him on a bad day.
“It will not the first time a footballer comes into the manager with all sorts of problems.
“But it was a bit of a blip and, hopefully, that’s behind us now. I look at it and he’s with us, he’s happy and David Moyes has to be thanked for that, Sir Alex Ferguson also.
“Because I don’t like the idea of Wayne Rooney not playing for us.
“Whenever I go into the dressing room everything seems quite rosy at the moment.
“Hopefully, we will keep seeing that big smile on his face every time he scores.”
