First of all, I think Sergio Ramos is one of the greatest centerbacks of all time and certainly the most interesting. One thing I've noticed with almost all centerbacks's physical stats the aggression is fairly low (75-82) or in that range. Well guess what. This guy is 90 and I am not gonna complain. It seems like agression is only an ai stat but even playing with him I can feel his emotion. So now let me actually give you a review. When I bought him he had backbone and until a couple weeks ago I had used it. He was very good, stand and slide tackles were excellent and even though he's short (for a centerback) he has a great presence and can be commanding against almost every striker. His pace wasn't great though and through balls in behind could really destroy me sometimes. A few weeks ago I switched to shadow and he has been even better. He can keep up with most strikers and alongside varane he doesn't need all that much pace. One thing I've noticed is that his penalties have been surprisingly bad and he got a lot of them saved (I think because of shot power) so now I use De Bruyne or Pogba instead on penalties. I don't really car all that much though. He is really, really good at getting a foot in before a forward can take off and even when they try to shield the ball he can tackle them, or foul them and get booked sometimes :). I do wish his defensive workrate was higher because then he would have better marking and would track players's runs better but again alongside varane most the time it's fine. Here is the squad I use him in currently: https://www.futbin.com/20/squad/16163544.
Dribbling actually pretty good
Medium defensive workrate
IRL he is such a set-piece threat but in FIFA he doesn't really find the ball on corners because only 6 feet and defense has their biggest guys back to defend corners
penalties again are good IRL but it doesn't matter because I just stopped using him for them
