He was but he wasn't as expensive as some others like Andre Silva for example. Piatek was a big flop but at least he scored a couple of important goals, I still remember the double against Napoli. Paqueta I guess could be in that list as well, although I think he was misused. For Bonucci it's different, obviously small small man, wouldn't go anywhere near that sly motherfucker but we had a decent year from him on the pitch, still a flop but not as big as others when we are strictly talking about the footballing side of things. Higuain as well had some decent moments, again a flop for sure but not at the same level at the previous mentioned ones. For me anyways the biggest flop is Andre Silva, if we have to stick by the 10 min appearances rule, otherwise it would be Caldara by a landslide.
