Manchester United boss Erik ten Hag insists he's happy with the form of Lisandro Martinez.
The Argentina defender was part of the team thrashed 7-0 at Liverpool on Sunday.
But after their Europa League win against Real Betis, Ten Hag said: "It is fantastic to work with him because he has such capacity and because he wants to develop every day.
"It's nice to see his type of defensive game. His attitude everybody loves it, the fans love it, the defensive line loves it. It gives the team strength. When he has the ball he is also good.
"I like him as a player. I like the attitude, and I hope we can work together for a long time to come."
