Jose Mourinho has slammed Frank de Boer as "the worst manager in the history of the Premier League" after the Dutchman said it is "a pity" Marcus Rahsford is playing under the Portuguese at Manchester United.
De Boer had praised Rashford after his impact in Saturday's win over Liverpool and said it is a "pity" the 20-year-old plays under Mourinho at Old Trafford - prompting an angry response from the United boss.
'If he has one or two not good games, he puts him out.
"If you go to his numbers and how many games he played with me".
You could see he wasn't right - everything which was easy for him previously became a difficulty and Rashford's natural game had vanished as a effect of not having a rest.
Frank De Boer was appointed Crystal Palace boss on a three-year deal at the start of the season, but was sacked just 10 weeks into the job, having overseen a run of 4 consecutive defeats in the Premier League, without his side scoring a single goal.
"If he [Rashford] was coached by Frank, he would learn how to lose because he lost every game", Mourinho said. The brace on his Manchester United debut followed by another two on Premier League debut, the Manchester derby victor, an England debut goal and Sunday's double against Liverpool instantly come to mind.
As for Rashford, we doubt the young local kid who scored both goals in a 2-1 win over Liverpool has too many complaints about his lot in life at the moment. I have to be honest and give the credit to the people of the academy that were responsible for his formation, and to Mr (Louis) Van Gaal who was responsible for his first season.
Mourinho believes United will have a chance of winning the trophy if they progress. "In the last eight you start smelling the semi-finals". But when a team arrives in the last eight, anything can happen.
Paul Pogba returns to the squad after a minor injury, but the club's record signing must do with a place among the replacements. "It's something that you have got to accept".
