Manchester United defender Lisandro Martinez has laid out his on-field attitude.

The centre-back's passion and commitment make him a crowd favourite.

And ahead of facing Newcastle in the Carabao Cup final, the Argentine — nicknamed 'The Butcher' — admits it is difficult to control himself sometimes.

Martinez, 25, said: “Yeah. It is hard. It is really hard. Sometimes I want to kill but you have to control as well."

The 25-year-old Argentinian World Cup winner produced a typically full-on display in the 2-1 win over Barcelona on Thursday night.

Now he wants to put on that same show of typical Argentinian spirit beneath the arch against the Toon.

Martinez said: “Argentinian players are always like this, we are passionate.

“Football for us is everything so that is why we always give everything of us.

“As a kid, I remember when I was really young, like four or five years old, I would start to fight and start to cry when I lose, so it is something we have in the blood, we have in the heart. It's our culture."
