Manchester United announced on Sunday that they have agreed to sign Lisandro Martinez from Ajax.

United have agreed to pay £57m for the Argentine's services, per the BBC.

Martinez will join the club when a medical is completed and player terms are finalised.

Martinez will be reunited with Erik ten Hag at Old Trafford. The two worked alongside at Ajax, with Ten Hag bringing Martinez bring the defender to Amsterdam in 2019.

Martinez stands at just 5 foot 9 inches tall. That's short for a centre-back.

However, despite his stature, Martinez earned the nickname 'The Butcher of Amsterdam' during his three-year stint at Ajax.

So, why is that?

Martinez is a tenacious defender who isn't afraid to smash into players and throw his weight around.

And footage, compiled by YouTuber user KaiiZoFilms, shows him doing just that. The 12-minute video, titled 'Lisandro Martinez Too Small? Okay, WATCH THIS!' displays that his height will not be an issue at all.

United have spent a lot of money on Martinez but he could well be worth every penny.

Speaking of his nickname, Martinez said, per the Mirror: “Yes, I am called the carnicero – The Butcher of ­Amsterdam. We Argentines do ­everything with passion and when I go out on the pitch, I fight for every ball. If I have to step over dead bodies, I do it.

“I want to win every 50-50 situation because I know that I am fighting for food for every member of my family and for my friends. That is the feeling I have – and every Argentinian has. It is the kind of ­motivation I cannot explain.

“I got my talent from my mum. Next to her work, which was a really hard job, she is also a good footballer. She still plays! She is a fantastic ­midfielder, honestly. She is older now, but she is still playing.”

He added: “Cannavaro was ­comfortable on the ball. And, despite his lack of height, he challenged for every ball as if it was the last tackle to win the game. I loved that style – and I am just like him."

If the deal is completed in the next few days, Martinez could make his United debut in their friendly against Aston Villa on July 23.
