NIF Bonucci is an exceptional card, certainly one of the best ball playing center backs in the game. His passing is crisp and accurate, which is helpful if you play a possession-based game or if you like to play long balls from your defense on the counter attack. He has low agility and balance, but he doesn't feel very clumsy and he is comfortable on the ball.
His standing tackles are incredible, and he tends to stay in position because of his work rates. He wins defensive headers, even against tall target men, but he wasn't much of an attacking threat for me from set pieces.
His stamina (73) is acceptable for a CB, especially one with L/H workrates. Even if you go on the occasional dribble with him, he will be completely fine to play the full 90 minutes + extra time without any issues.
Obviously, the only thing Bonucci lacks is a burst of speed to catch up with attackers who have broken through the defensive line. He's not slow, but he struggles to keep up with quicker players. Luckily, his good positioning and precise tackling make this less of a problem.
Lacks Recovery Speed
Bonucci is a defender that can actually defend, something that is hard to find on FUT 18.
He is a brilliant tackler and his work rates are perfect for a conservative CB.
Hardly any of his passes are misplaced and he is rarely causing mistakes.
His strength makes him effective against quick players as he can muscle them off the ball.
His pace however isn't great so partner him up with a defender with at least 70 pace.
I started by using Bonucci in a classic sweaty Serie A alongside Manolas as a LCB. He definitely was the stand out player in defence. Even though Manolas has an extra 12 pace, Bonucci still seemed to be able to handle the insanely pacy attackers one tend to come up against all the time. Late I used him in another squad, where he played RCB - this perhaps suited him the best. However, he definitely can play both sides.
Now, I tried about 10 of the OP CBs this year (the pacy ones who goes for 1-10k), but IMO Bonucci outshines all of them.
This being said, I haven't tried Ramos, Chiellini or Boateng, who are all more expensive, but on paper have better stats.
Top notch defending, especially remarkable standing tackle, sliding tackle as well as interceptions
Compose on the ball for a centre back, which is really good when positioning him for passes
Great passing, both short and long
190 cm, 88 heading, 85 jumping and 85 strength makes for a great player in the air, both when defending as well as at corners
For a centre back, he actually has ok stats for long shots - this is not a thing I ever tried with him though
Low/High work rates
Relatively slow compared to the sweatiest defenders
