I dont see what the big deal is, it's just Italian hot headedness. Happens all the time, few examples are Capello chasing Cassano round the Madrid training ground with a broom, di canio and everyone he encounters pretty much.
Training at top teams is supercharged, everyone wants to stake their place and some times it boils over. Happens all the time. Only people who make a big deal of this are the people who aren't involved.
Fuck the British Media, contributing to the downfall of our society for years.
