Manchester United boss Ralf Rangnick admits Marcus Rashford isn't doing enough to warrant a start.

Rashford is enduring the first real crisis of his playing career, bereft of form and confidence, and without a goal in his last 11 games for United.

“I was not a striker myself as a player, but as a striker we all know it's all about playing well, scoring goals and getting assists," said Rangnick.

“If that doesn't happen over a period of time, it's not so easy. As long as he's trying to give his very best - and he did that in training.

“There were quite a few training sessions in the last couple of weeks where he trained on a really high level and that's why I always gave him the chance to play again.

“As long as he does that, he will always be on my list to play and be in the starting eleven.

“In the first 20 minutes against Aston Villa he was good, he was on fire, he was emotionally involved.

“Then, after the first 30 minutes, he got worse and he didn't play on the same kind of energetic level he did in the first half an hour.

“It's about showing that on a regular basis and continuously playing on a high level and again, for him, there is still room for improvement but the same is true of other young players.

“We have so many top, talented players and we have to work and develop as a team together."
