Mourinho insists Chelsea did not move for the new United fullback over his personal demands.
The Mail on Sunday says Van Gaal knows Mourinho tried to hijack Shaw’s £27million summer move to Old Trafford at the eleventh hour and is angry he is now trying to effectively portray the 19-year-old as a money-grabber.
Chelsea were still in the hunt for Shaw on the day that United announced they had got their man and tried desperately to get the young England left-back to change his mind.
A senior source close to the deal confirmed: "They (Chelsea) pushed, very hard. Even up to the final hour."
