Lisandro Martinez gives thoughts on Andre Onana's rant at Harry Maguire

Lisandro Martinez has insisted that Manchester United will 'better' if players call each other out for losing focus after Andre Onana ranted at Harry Maguire in a pre-season defeat.

Man Utd were beaten 3-2 by Bundesliga outfit Borussia Dortmund at Allegiant Stadium in Las Vegas at the weekend, and the most talked about incident that occurred in the game was undoubtedly Onana's outburst at Maguire.

The Red Devils' new goalkeeper, signed from Inter this summer for a £47m fee inclusive of add-ons, rushed across his penalty box to lambast Maguire after an ill-timed pass from the ex-captain led to a chance on goal for Dortmund.

Speaking about the incident to the press, fellow defender Martinez revealed his belief that such incidents are a good thing as they ensure the team is 'really sharp'.

"It's better for [it], it's better for [it]. If you are focused, you can fight with your teammates as well, you need to make sure everyone is really sharp, but nothing happened," Martinez said.

"It's part of football. He has a big personality. He can play football, he can deal with the pressure, he's really positive, he's a leader, that's the style of Manchester United."

Onana also commented on the incident in an interview with MUTV, saying: "I try to demand a lot from him because I know he is a good player.

"He's one of the captains of the team. He's big, he's good with the ball so I will demand [from] him a lot. He's a great guy, I have a good relationship with him. He has to be ready because when I'm on the ball I demand to everyone a lot - I start with myself because we are in this together. 

"Mistakes come but we don't have to be afraid to make mistakes because this is a part of life and we learn from the mistakes.

"We have to be very critical with ourselves. If we want to win prizes we have to demand a lot. It's a big honour to be here and I'm very happy to work with these guys - Harry is a fantastic player so we will move on."

Man Utd will round off their pre-season preparations with a pair of friendlies this weekend, taking on Lens at Old Trafford before facing Athletic Club in Dublin.
