I call people and things fag/gay often (
I'm pro-gay), but that's with friends. It'd be stupid to say that at work. In Sarri's case, it's even stupider because he's a public figure.
For that reason, it should've been a ban worth a few matches that includes Serie A matches. Banning him from two Coppa Italia games is the same as no ban and no punishment for being retarded.
Mancini's reaction is definitely funny and not genuine. Most hilarious part of this is probably the rule and administration of the rule according to which Sarri would have been banned for as much as 4 months if Mancini were gay, but since Mancini isn't gay, it's practically nothing and only worthy of a slap on the wrist.
