Former Manchester United captain Nemanja Vidic admits he's been impressed by Lisandro Martinez.

The Argentina defender's season has come to a premature end due to a metatarsal injury.

But Vidic told FIVE: "I like him, he likes to defends and that's why I saw when he first came. Obviously, I had doubts when he came because of his height, but he is good in the air and he's got away with his height.

"He knows how to position himself, I think he's a good character and good for the dressing room because he has that winning mentality, he's a fighter.

"He likes to defend, that desire you need to have on the pitch and you have to have certain players doing this 'energy lifting' and he does that. Unfortunately he's injured now but he's definitely a great signing for us, he did great."
