Manchester United defender Lisandro Martinez says the players should have no problem with the demands of goalkeeper Andre Onana.

The pair played together at Ajax.

Lisandro said: "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. It's part of football.

"He (Onana) 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."
