Tomori said: “Obviously it will be nice to see him again. We played a lot of games together. However, there will be no pleasantries once the teams step out onto the pitch.

“It will be nice to see him again so soon after he left, but we are professionals. When the game starts, friendships go out of the window. We want to win. After the game we can start being friends again. During the game, though, we are not friends.”

Milan head into the match off the back of a damaging 5-1 loss to rivals Inter on Saturday. Newcastle, meanwhile, picked up their first win since the opening day with a 1-0 victory over Brentford.

Tomori knows Milan are in for a tough game. He added: “They [Newcastle] are a very strong team, with legs up front and physicality at the back.

“They like to play it deep. We know what we’re expecting from them and then we have to demonstrate our quality with and without the ball.”
