Radja Nainggolan futmas is a complete midfielder, he can play in every part of the field, can be decisive towards the goal and decisive in defense to stop an important attacking situation from the opponent. Every longshoot is almost a goal, every pass is accurate (long or short) and he's also a clinical finisher. Can't be so accurate with his heading and he's not so strong against physical opponent, but you can easily sliding tackle them to grab the ball and do a fast counter-attack with him. His stamina is unbelievable, you can run everytime and do extra-time without any problem to change him, he just lasts until the last breath. He's not so fast.
So as he played as CDM in the 4231, he didn't make as much goals as he's actually able to do in his potential, if you play a 4312 or a 41212(2) he's a must-have CM/CAM, however i liked as CDM.
Complete midfielder, can be decisive for defensives or offensives situations.
Tireless and engine
3 Weak-foot, but it's not a big problem.
