Nice post, tending to be objective. I've watched some of his matches but when I see him playing as a CB, lose interest. Gotta say, I liked him, but you seem impressed. Guess it's due to a really small sample (my). That said, would be good if he started playing as a midfielder. Albeit, from what I've seen, he could make a libero. What position(s) in the midfield do you think he could occupy?
Ah, just remembered.... would you bring him this season if had a chance?
I think he could play Busi's role or as a center mid. I would prefer CM because he would have full freedom to dribble and roam around wherever he wants. However, I could see him playing well at CDM too because he has more space for long balls and progressing the ball from deep in the midfield. He's also press resistant which you need for both positions, whether or not he's good enough defensively to make an elite CDM I couldn't say for sure.
I agree that playing at CB is a bad situation for him. But to me the confidence with which he attacks and creates plays from the CB position shows a fierce confidence in a very young player. Best of all he doesn't make many mistakes doing it. He plays any vertical pass he wants to in that league. Think of how many players have been able to play like that from CB, ever? Even though it isn't an elite competition that's impressive.
I would get him this summer if that means the price doesn't go way up next season. If he gains traction by playing in midfield teams like City or PSG could pounce, raising Ajax's price. But I don't mind letting him stay there till next summer if it meant we pay up front and loan him back.
Real Madrid has made a habit of buying quite a few young players on faith and hoping some would pan out successfully. All of the transfers, even the ones that failed, were good investments. Guys like Danilo, Morata, etc. They didn't make it but were good players to bet on. Varane, Carvajal, Isco, Casemiro, Asensio, and Kovacic are all relatively cheap purchases that have made a pretty big impact on their success. They also invested in James who was a success but left for Bayern. We've made some pretty bad decisions with our investments. Guys like Arda, Gomes, Paulinho who could never reach star level play.
We have started going down a good path with transfers like Dembele, Arthur, Malcom, Umtiti, and Semedo. De Jong is another one I think that could put us back on the very top. Hopefully when that young roster matures our team can phase out of becoming dependent on Messi and rather making things easier for him. If Dembele achieves his potential I think we're in a very good position for when Messi finally retires too.
