As I said in the midfielders rumors thread and as I said back in the time when we were firstly linked to Schelotto, Bonaventura is the guy to take from Atalanta, not fucking Schelotto, or Cigarini.
I am fan of his. Thought he'd be huge few years back, but he didn't develop as I thought he will. Maybe being played out of position did it's job. He is natural central minded player, CM or AM, as he has said himself. He has been played as LM and sometimes RM most of the time. He is complete player, dat can pass, bang a few goals, is calm on the ball and all that shit. His stats are not impressive, but bare in mind all his goals and assists are form open play, as he doesn't take set pieces, as that's Cigarinis job.
Will never bee a world class, but he is consistently good to great player. Rarely has BAD games. Could be caluable rotational optin that can cover pretty much every position in the midfield or even be a SS (i dont personally see him there but you never know). He is also not very expensive and has low wage, is home grown and won't cry over a starting place. He is also at the best age who is yet to enter his prime. He is 24 I think.
That being said, I'd definitely take him, unless the price is over 7-8 mils, that's a bit pushing over.
He may be a flop as well, but i doubt, since as i said, he has been consistent player that always does his job.
