He was doing ok lately, but not in the role he was supposed to excel from his early 20s.
Nowadays he's more a free-role CM who can roam into the box occasionally, but whose main duty is to dictate tempo in midfield. If he were a little bit better defensively, he would actually become a good regista
He's massively improved his passing skills since joining Sassuolo, but he's also lost a lot of speed over the last 6 years, following some strings of injuries and also after failing to play regular 1st team football even when he was actually available. He's also much less agressive when attacking, but slightly more supportive in that stance instead.
I think he finally found a place and role at Sassuolo, but it is a shame he took some much time to find it.
