AC Milan coach Stefano Pioli says their clash with Porto will be decisive to their Champions League chances.

Milan meet Porto in the next two group games.

“We face a solid, compact opponent," Pioli said at a press conference. “They have fast attacking players and a well prepared coach.

“It will be a match that will present difficulties that are typical of high-level games.

“The two games against Porto could be decisive for the final outcome.

“[Rade] Krunic can start the match, he fights for the place with [Daniel] Maldini. Rade is fine, he can either start or enter during the game.

“[Ismael] Bennacer is fine too, he's ready for tomorrow."

He added: “We must remain focused and clear-headed in every situation. We have paid dearly for every mistake: we need total attention.

“We lost the first two due to two moments of carelessness."
