Casemiro is undoubtedly a very good player in this game depending on whether he fits your style of play or not.
I was trying Fernandinho in a 4321 but realised I could do with a stronger more defensive type player so I chose Casemiro.
Although Fernandinho was better on the front foot Casemiro provided so much defensively with his defending and physicality doing wonders.
Lets get into his base stats.
Pace- Really not horrible. He cant blister away from other players but he can certainly hold his own when there is grass in front of him.
Shooting- Really good from outside the box. You can never time finesse it with him though it must just be straight up power.
Dribbling- He can control the ball and pass it off nicely but cant dance between defenders because of the agility and balance issue.
Passing- Very good passer to be fair. He has chipped in with a few assists in his time in my team.
Defending- Brilliant Tackler. he has very similar qualities to many CB's in the game meaning he puts in some clutch tackles to stop many attacks.
Physical- Very Very strong. He is able to very easily push many attackers of the ball such as Mbappe, Neymar, Martial and Lucas.
Honestly if you look at his stats and you aren't to fussed thats fine. Give him a try though he may just be the extra defensive player you are looking for.
