AC Milan defender Davide Calabria was left disappointed with their Champions League defeat at Porto.

Luis Diaz struck the only goal of the game with Milan midfielder Ismael Bennacer appearing to be fouled in the lead up.

"I don't like to look for excuses, because otherwise it seems like we don't deserve to wear the Milan jersey. Some might be a bit off form, not playing for a while, which is to be expected," Calabria told Sport Mediaset.

“It went badly, there's no point crying over split milk, we have to prepare for the next match, remember we are doing well in Serie A and try to keep building."

Calabria said of the goal: “It looked like a foul from there, I haven't seen the replays, but VAR isn't going well for us recently."
