all this is true. But he still won the World Cup.
What did Conte do so far? No matter who is coaching Italy, i'd always expect them to beat teams like belgium or sweden, and sweden was a lucky win btw.
Italy is quite mediocre at the moment - yes, but You might have been brainwashed by german media, constantly talking about how utter shitty italy are. They just can't wait til Jogi gets his ass handed by italy once again.
