Manchester United manager Erik ten Hag has challenged Alejandro Garnacho to continue his development.

The Argentine winger put in one of his best starting displays for the club in a 3-0 win over Crystal Palace in the Carabao Cup.

Garnacho, who has previously been at his best as a substitute, scored the opener against the Premier League outfit at home on Tuesday night.

“You have seen at the start of the season [that] we played him… his contribution was not good enough," Ten Hag told reporters post-game.

“But he also had some good actions. You see always he is a threat in the game even when he is not playing that well.

“He has to learn when he does his job in defending he will always have his moment and he will always be decisive because he has great qualities."

“As well, it's not only off the ball," he added.

“But I want to see like today, he is entering the box in the right spot to finish.

“But I think it is quite normal for a player of his age that there is space for a lot of improvement.

“Everyone likes him, the fans like him, the team likes him, I like him but we also have to demand from him and push him because he can act on a very high level but he has to show it every day."
