Haisley absolutely loathes MLS, unsurprising to see an article like that from him.
Pirlo's mailed it in as a serious player anyway. He plays at 60% most games, which is usually good enough for him to still be a useful player in MLS.
Still not sure how Conte can justify leaving Giovinco at home, given A) the state of Italy's forwards and B) his form, regardless of the league. I guess Insigne has that "tiny, frustrating little attacker" role locked down already and Conte wanted bigger bodies.
