I was disappointed with many Prem CDM so far such as Matic (out of position most of the time), Gueye (kinda small and weak), Ndidi (reckless passing). Then, i try Dier gold card, feel so reliable to use him. Then, i go to this special which even more surprising good and always appear at the right time when u need him. He's so good at bully opponent central players with his powerful strength, and he's also dominate the aerial duel. He has "Dive into tackle" trait, which is very important for any CDM to easily win back the ball or kill the opponent build up. His pace is enough for a CDM, passing also decent, really a threat during corner kick and helpful when u conceded corner kick. Dribbling is not necessary for him, just pass the ball as soon as he receives the ball to avoid reckless mistake.
Overall, i really like this monster for his defensive ability and dominant aerial warrior.
DEF: Very good AUTO interception, strong tackler, and powerful heading for both attack and defend
PHY: Super strength for bullying, good height and jumping, fair enough stamina
PACE: Decent enough for CDM who has M/H that always lying at the stay back (better than Matic imo)
PASS: Decent enough for build up forward, but not a creator or long passer
SHO: Not for him
DRI: It's risky for him to dribble, always pass the ball to nearest team mate
