Conte should not be excempt from criticism and he has made mistakes in Europe, but "replace him when he doesn't improve in Europe next season" is just hilarious.
I agree about the wastage on Peluso, Padoin, Ogbonna, Isla, (loans: Anelka, Bendtner, Osvaldo) and several other youth players who I think won't ever feature for Juventus . . . . but what would you deem as success in Europe? what if we draw Bayern in round-of-16 next year?
