"If he was coached by Frank he would learn how to lose because he lost every game".
De Boer had claimed that Mourinho did not have the patience to let Rashford develop because he was all about getting results.
Manchester United manager Jose Mourinho has hit back at former Crystal Palace manager Frank de Boer after the Netherlands global said that it was a "pity" that Marcus Rashford was playing under Mourinho at Old Trafford.
"If you go to his numbers and how many matches he played with me last season and this season, maybe I am wrong, but I would say he is probably in the top five players with the most matches over two seasons".
'If he has one or two not good games, he puts him out.
"I think we're not one of the best teams in the competition but when a team arrives in the last eight, anything can happen", said Mourinho, who said Paul Pogba did appear for a "little bit" of training after missing the start on Monday morning but was unsure if the midfielder would be involved.
Rashford is set to keep his place in the starting line-up after his weekend double for tomorrow's Champions League last 16 second leg against Seville.
De Boer, who lost his job after five games and 77 days in charge of Crystal Palace, suggested that the pressure on Mourinho to get results is hampering Rashford's progress.
"Frank De Boer, seven matches seven defeats and zero goals".
Rashford has made 93 appearances since Mourinho took over from Van Gaal in 2016.
After a goalless draw in the first leg, United need a win to advance and Mourinho will hope his side can continue the momentum of recent matches in which they have beaten Chelsea, Crystal Palace and Liverpool. "And Marcus is having these experiences". He plays for United many matches, he starts some comes from the bench for others.
"Tomorrow is a very hard match, we are playing against a team that didn't lose against Liverpool home and away", said Mourinho. Of course not. He's a player we trust. "Analysing a performance for me is more than number of goals or assists, and for me I'm really happy with Marcus".
