Manchester United fullback Luke Shaw has heaped praise on teammate Lisandro Martinez.

The Argentine center back, who won the World Cup with his country on Sunday, is a fan favorite at United.

Shaw explained how it is like having Martinez as a teammate, while talking about the rapport the passionate defender has already built with the United supporters.

"[He has been] unbelievable, to be honest. You can see everyone loves him," Shaw explained.

"The fans love him. His left foot is unbelievable.

"I think it always helps when you play with a left-footer on the side because he naturally likes to come out to that side, and I think he has fitted in really well. Of course, he can keep getting better and better, but for me so far, he has been unbelievable this season.

"He needs to keep that up. His aggression, his passion, we need him in that backline.

"He brings that every game. I am really pleased to have him in the team."
