I never denied his qualities, I just don't like him as a player since his Ajax first season. When he signed for Juve I tried digesting his camelness but I couldn't, not because of Del Piero (Del Piero's thing forced me to hate Capello not Cadabra like many think, Zingaro was already disliked in my book before he signed for Juve). Then when he played for Inter he reached my most hated player list and not because he left Juve, I was happy he left in calciopoli, but because the whole Inter environment + calciopoli + Mourinho's 1st season + their fans and his ego etc made him top the list.
Last but not least, hate aside, sands cleaned, I seriously don't think he will improve anything in Juve's attack, I don't care how much he earns or his price tag. What will improve this Juve IMO is someone hungry for success who will play for the kit and fit in Conte's tactics.
However, if he signs for Juve, I'll still sleep well, I wont care that much about CL if he's part of the team, Juve will still win the Scudetto with or without him.
