let's hope. all rugani needs is some ruthlessness and aggression, but that's very hard to learn if it won't come naturally. current rugani would be already a classy defender in the '80s, when football only started to be so physical.
i watched most atalanta el matches, and at least 10 serie a games just to see caldara. my cable supplier has 3 own sports channels, and they broadcasted the serie a and the el, too. as they got 3 channels, sometimes they showed 3 matches of either competitions simultaneously, so i was lucky enough to be able follow calrada from week to week. he's fucking good. no wonder that not a single italian fan fancied the idea of giving him away. he's very disciplined and intelligent in positioning, too, so moving to a back 4 shouldn't be a problem for him on the long run. he also has (had...?) chiellini and barzagli to directly learn from. his only weakness is his passing game. it's not that he gives away the ball too often, it's just that he's no bonucci or rugani (who's an excellent passer himself).
i still have some hope that we include recompra in his contract. milan might break his progress, though.
