This season, the 20-year-old attacking "red devils" Marcus Rushford continues to steadily progress, as evidenced by his winning double in a recent match against Liverpool.

However, according to ex-trainer Ajax, Inter and Crystal Palace Frank DeBur, the further development of Rushford would be more rapid if MJ was headed by another coach.

"It's unfortunate that Rushford's coach is Mourinho," said De Boer.

"Marcus is an English football player, so I would like him to get playing time, despite some mistakes. Mourinho always requires a result, because after one or two unsuccessful matches, he will remove him from the ".

"Marcus is very young and talented. He needs to play - this guy wants to see on the field every week, "- concluded De Boer.

This season, Rushford took part in 27 of the 30 MJ fights in the Premier League, scoring 6 goals and giving 5 assists.

Previously, Mourinho has already responded to accusations that he does not know how to work with young players, leading Rushford as a good example.
