I really like Belotti. He's strong, quick, finishes comfortably with both feet (not to mention his head) and has an incredible attitude on the pitch. He works so hard for the team in every game. A dream to have as a teammate. It makes sense that Arteta is interested. He'd have to step up his goalscoring a fair bit to play regularly for us, but I think he could do it surrounded by better teammates. Torino are crap and he has singlehandedly saved them from relegation at least twice in the last few years. It's not easy to get goals there.
You have to think Arsenal would be an attractive destination if he leaves Turin. I can't see him going across town to Juventus, and I don't think Inter want or even have the means to take him. That leaves him with the option of going to a middle-sized club like Roma, or going abroad where he'll be offered much better wages and a bigger chance at trophies.
