Manchester United manager Louis van Gaal wants England boss Roy Hodgson to clarify comments made about Luke Shaw.
The United left-back is currently out with a hamstring problem but his club manager says that has nothing to do with his general fitness.
"Roy Hodgson cannot judge at this moment," said Van Gaal.
"I have never seen him here at a United training session."
Shaw will not be part of the England squad for the forthcoming internationals against Norway and Switzerland.
"If Louis thinks that he can get him fitter then I'm sure he will certainly have our approval," Hodgson said.
Van Gaal believes the comments were inappropriate after Shaw worked hard to put his early-season fitness concerns behind him.
He added: "I think Roy is referring to the World Cup. It is possible, I don't know. That is what I want to ask. But now Shaw is doing a great job."

The Dutchman, 63, continued: "In the United States I said to Luke, 'you came here and you were not fit'. I changed his programme and he did everything that he had to do to be fit.
"Now he is an example in the dressing room. He is training fantastically."
