AC Milan defender Leonardo Bonucci admits they're lacking character after their 0-0 draw with Europa League opponents AEK.

The result was earned in Athens and leaves Milan coach Vincenzo Montella under pressure.

"The two games against AEK were strange, as they were often man-marking us and tried to crowd us out everywhere except in defence," the defender told Sky Sport Italia.

“We knew it would be difficult, but we picked up a good point and will now focus on the game with Sassuolo. We want to get back on track in Serie A."

On Montella, Bonucci added: “We are the ones who step on to the field, it's not just the ideas of the Coach. We need to get results to bring back the enthusiasm we had this summer.

“I see a lot of quality in this squad, but we lack a little bit of character and confidence to take more responsibility when the ball is at our feet."
