I'm not giving up on Leo yet. Granted his mistakes are very costly, and he's far from a great defender (seems to be very rash under pressure) but he's not a completely useless defender either. Just needs some tweaking and improvement.
I get so nervous when Bonucci starts running with the ball from the defence & there is no option for a pass. It would be easier to give him an opposition t-shirt & mark him out of the game.
Easier said than done. That's his Achilles heel right there. However, thanks to Borriello, Bonucci is no longer public enemy number 1, and the biggest problem on the team.
