Criscito will come back. And I have seen him perform well enough lately to have little faith in his abilities. He deserves a second shot, and he will get it IMO, more then good enough as a squad player at the least.
But what you are saying is NOT dickriding at all IMO. Firstly, Juve disgarded him like a bad habit, even if he wasnt on too good of a start, it was bit harsh. Competitive and callous sport it can be at times. Secondly, you have to know his relation to those clubs you mention, he doesnt want to go there simply because they are decent Serie A teams. But he has close ties to them.
Genoa because he was basically nurtured there, we signed him from their youth set up, he played in our primavera too, but he was a signing to the primavera from Genoa. And then later on went back home to Genoa so to speak for 2-3 years now on loan. So you would understand why he is fond of them.
Napoli because like its common for italian players in a way, he is from there (several are in calcio, in our youth products alone, Criscito, Palladino and Nocerino is, perhaps Lanzafame too). He is probably, naturally a Napoli fan due to that and hence, wouldnt exactly mind going there if we dont want him. And we havent really shown we do.
