In the overrated camp are Modric and Ramos.
I admit, they are perhaps the best in their positions in the past 3-4 years, but esp. Modric hype has reached a new level after the Argentina result. People seemingly forgot all the games he was bossed both for Madrid and Croatia. Argentina are a shambles of a team, and other teams have beaten them comfortably too. This season, Modric and Madrid were bossed many times both in the league and in CL. International football wise, Croatia has a good team but haven't done much at all, Iceland finished ahead of them in qualification, haven't they?
Ramos, on the other hand, is a rash, dirty defender. He is playing in an era where there are very few great defenders, to be fair, and that alone puts him into the mix of "the best defenders of his generation" category. However, if you look at his playing style, fouls, cards, and brain dead moments, he just shouldn't be mentioned alongside historical greats.
So the above 2 at the moment are overrated.
