Momo is a devastating player when on his game. Ranieri's tactics obviously got the best out of him, as well as being paired with Zanetti.
Perhaps he can offer us more in another set up, but not with this current Juve team/tactics (I'm not implying that we should change the team/tactics to suit him. Just a general observation)
Regardless, he is hardly the biggest problem with our starting 11 and I still believe he has a future with us. I would definitely listen to offers, but getting rid of Momo is not a priority, unlike so many other players on our team.
