Well tbh he played more games, cause Villareal was in Europa League semis (15 games), while Atletico didn't get out of their group(4 games). That's 11. Other 4 can be anything.
Also, you assume that I use those stats to downgrade Rossi, while fapping to Aguero. All I do is pointing out that Kun had actually better numbers, when you look closely at them. I will be happy with any of them in Juventus, as they are both an upgrade for sure.
