The Italy midfielder, 23, could face a lengthy ban, but Howe is grateful for the support he received from the fans.

"I think the hardest part is ahead regardless of what happens," he said.

"Immediately, you get a lot of attention and people are talking about the situation. He's had the love of the supporters today, but that's difficult to maintain over a long period of time. Who knows what's ahead?

"I just think it's great for him to know he's got the support, not just of the senior management at the football club and the manager, but also the support of the supporters and they're the most important people."
