The millions on Patrice were very well spend, so don't be so harsh.
He was really usefull in his first two years for us, but now he is getting older. It's natural that older players will slightly decrease. He is a big factor in the dressing room, but if he wants to leave there is no reason to hold him on, because quality-wise Alex Sandro is better.
If he leave I will really thank him for coming to Juve. United didn't want him anymore and we could pick up him for a few millions. He let us all see why he deserve the Juve shirt and he was always happy by Juventus. Such a warmhearted and intellegent footballer instead of a money searching guy who got lucky to be footballer because he is dumber than the simplest roadworker.
