Lol, because he's an accomplished coach and I'm not, I can't have an opinion about his approach? There are different ways it could have been approached. Ferguson, Lippi, Allegri, Pep, Ranieri may have all reacted differently, for better or worse.
Just because he's an accomplished coach doesn't mean he can't get things wrong. And in this case, he could have handled it better IMO.
Or maybe we shouldn't have opinions about what accomplished coaches do, be it interviews with the press or tactics, since we don't know jack shit?
