Its probably a lose lose scenario for a goalkeeper to do a free-kick drill with your 45 year old manager.
Ac Milan manager Massimiliano Allegri rained shots down upon his young Brazilian goalkeeper Gabriel and wasn't shy about giving him some unfriendly advice.
Allegri was a decent midfielder with Pescara and Napoli and as this video shows, clearly has some gas left in the tank.
