It's only his aerial ability which poses real concerns for me.
He's obviously a guy who loves to defend, happy to put his body on the line whenever needed, strong in the tackle, lightning quick. Overall there's a lot of raw talent there.
I think I've heard it mentioned that he actually hasn't played much professional football for a guy his age, he certainly plays like that's the case. I think if treated like a 21/22 year old centre half who still has a lot to learn in order to make the most of that raw ability I think he can become a fantastic player for us.
Patience patience patience. We all know what happened with our resident Swede (I was among those who wrote him off as a lost cause, I'm ashamed to admit!).
Having said that I'd love to see a De-Ligt / Skriniar / Koulibaly type brought in to replace Jones & Rojo, with Tuanzebe brought into rotation alongside the new signing / Lindelof / Bailly / Smalling.
