Ruben Amorim has told Marcus Rashford he wants him to stay at Manchester United.
Rashford has suggested he's ready to leave and pursue a "new challenge" after a 20-year association with the club.
Amorim, however, insisted the 27-year-old can find that challenge at Old Trafford as he looks to return United to the top of European football.
"We have here a new challenge," Amorim told a news conference on Wednesday.
"It's a tough one. For me it's the biggest challenge in football because we are in a difficult situation and I already said this is one of the biggest clubs in the world.
