Very very weird
I have used flashback eder militao as a staple in my defence for a few months now and the only way I can describe him is weird. He's incredibly hot and cold, often will make incredible slide tackles and blocks yet is unable to win a 1v1 against any attacker with high strength and/or aggression. His in game stats in no way reflect his in game performance. He turns very slowly despite having decent agility and balance, and doesn't feel like he has 91 pace. My main issue with him and this might just be me being bad at the game which is true, if he ever wins a scrappy tackle against an attacker he'll always get tackled straight off the ball again. That may be me not clearing the ball effectively however I don't notice it with other defensive players I use, I think he just has a real lack of physicality in game.
Overall he's a solid CB, will win you games with moments of brilliance and has fantastic links to better centre backs, however I find his lack a strength and aggression a real issue.

Shooting (He's very decent at a short range powerful shot in the box, especially after a corner has been delivered)
Agility and Balance
