Man Utd star Lisandro Martinez insists secret to his success is being a ‘good human’ and not a ‘know-it-all’

LISANDRO Martinez believes he has won over his Manchester United doubters – because he’s shown he is a decent human being.

Some Old Trafford fans voiced concerns over the central defender’s lack of physicality after his arrival from Ajax.

But Martinez has proved his worth for Erik ten Haag’s men and has now overtaken Spurs hardman Cristian Romero in the Argentina pecking order.

The United man said: “My advice to anybody is to have a good lifestyle and to share your experiences with the more mature players.

“You have to be ready to learn from other people and listen to what they say to you.

“But above all, you must not be arrogant, not be a know-all, to be disciplined and have good human values – to be a good person.”

Those virtues will not spare Martinez and his team-mates from the brickbats of a devastated nation if Argentina’s World Cup ends tomorrow night when they take on Poland in the Group C decider.

And he knows how deep the devotion runs – both inside and outside the dressing room.

Martinez added: “I feel what it means to play for Argentina.

“We have a living relationship with the fans and it motivates us every single day because we know how much it means for them.

“But the key for us now is to remain calm. We can’t afford to overload ourselves with too much pressure.

“We know how important it is for each of us to represent Argentina and wear this shirt. We have to give everything but you cannot do that if you are not calm.”
