It's no exergeration to say he could become one of the best CMs in the world. There is not one area of the pitch he doesn't look at home in. He's got the lot. Great touch, acceleration, incisive passing, intense pressing, tackles well on his feet, can strike it so well, tricks, the lot.
The extended break has given his body the time to properly heal and he's playing like he belongs now.
Everyone talks about him unlocking defenses, but it's his pressing ability is what he makes him so dangerous. It's ridiculously effective.
