Seriously, looking through here, and in reflection of the CL final. I'm of the opinion that Juventus management should have literally sat Tevez, Vidal and Pirlo down in a room, separated from everyone else; and said something alone the lines of "We don't want to get in the way of your wishes, and if any of you want to leave that is fine, but given the importance that each of you bring to the team, we can only let two of your three leave in one season."
I would've picked Tevez to have stayed, a year ago, I'd have chosen Vidal; however I feared he was going to grow into a liability in time here, though he was a legend in his own right.
