He absolutely is - at least for true CMs (not attacking midfielders). Whos better?
I wouldn't call him even a pure Cm but a double pivot player from Tite's 4231.
His natural instincts are: a pure pivot, how to not lose the ball.
He looked like a CM only in wild matches when he was avoiding the opponents who were running at him.
But even then, he acted more as a pivot who was pushed further up the pitch than a CM who plays football in 3 ways: defending, build up and attacking.
His whole build up is kind of: avoiding pressure build up. And not some: oh, there is NO pressure at all. Let's take a ball and ACTIVELY create a good assist for our teammates because we need to score a goal.
I think that a hype around him will drop a lot during this season.
More and more people are starting to quietly mentioning how he needs to improve his attacking skills, be more brave in the attacking third.
That's how these things start on our forum.
1. at first a player is perfect and an amazing talent (insert Dembele, Malcom, Samper, Alena, Bartra, any La Masia talent here)
2. then, there are no flaws and if someone says that there are flaws, he is an idiot.
3. then, a few Months later, when users accept that some minor flaws exist, then they are in a denial, and a coach, a system, a team playing opposite to player's strength, bad teammates or random excuses are guilty for those flaws. Never a player.
4. in the end, fans slowly start to accept that there are some flaws and then it grows and grows... But sometimes it takes 1 year and sometimes 3-4 years until we reach that level.
And especially if he really won't click well with a new absolute favorite Frenkie, the hype will wear down fast.
