AC Milan’s Fikayo Tomori relishing clash with former team-mate Sandro Tonali

England international Fikayo Tomori has warned Sandro Tonali that friendship will go out of the window when AC Milan and Newcastle head into Champions League battle on Tuesday night.

The two men were team-mates last season as Milan made it to the semi-finals of the competition and finished fourth in Serie A, but they will be on opposing sides at the San Siro following midfielder Tonali’s £53million (€61 million) summer switch to St James’ Park.

Former Chelsea defender Tomori, 25, admits it will be god to see his former colleague again – but only after the final whistle.

He told a press conference: “Obviously it will be nice to see him again. We played a lot of games together.

“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.”

The Italians will hope for a positive start to the campaign as they attempt to bounce back from Saturday’s 5-1 derby mauling by Inter, the side which dumped them out of the Champions League last season.
