In a proper counter pressing side. He'll be quality. It's no coincidence that he was really good in 24/25. Unfortunately I think he'd be good under De Zerbi for a season or two.
I think Howe completely lost his way tactically last season and it showed with Tonali more than others. His very poor passing is magnified in our side because we simply cannot keep the ball. I'm also not sure where he fits into the team.
If we got good money for him, he can go for me, but I think that about any of our players. It all depends on what direction Howe wants to go in really. If he wants a return to a high intensity press where we won't let teams settle, then surely you'd look to keep Tonali. If he's going to persist with whatever the fuck last season was, you may as well get him peddled.
