Manchester United boss Jose Mourinho mocked Frank de Boer after the Dutchman's swipe on Saturday.

Mourinho went after the Dutchman, having been irked by the former Crystal Palace manager saying it was "pity" for Rashford to be playing under the United boss given his preference for short-term success over player development.

"I read something, some quote from the worst manager in the history of the Premier League," the United boss said.

"Frank de Boer - seven matches, seven defeats [sic], zero goals - where he was saying that it was not good for Marcus Rashford to have a coach like me because the most important thing for me is to win.

"If he was coached by Frank, he would learn how to lose because he lost every game."
