He's the profile that Barcelona seem to yearn.
I think he was linked a few years back when he wasn't a regular for Chelsea and few here wanted him (same with Rudiger). But perception has changed with Tuchel Chelsea.
Will be a very good signing if he doesn't return to injury problems. Renewing Araujo and going from Lenglet, Umtiti, Pique, Araujo, Eric to Christensen, Pique, Araujo, Eric (then Mingueza or a B guy as 5th) is a shrewd move.
Pique goes in 2023 and you got Koulibaly, Skriniar for free or the 2024 expiring big hitters like De Ligt and Kounde to negotiate for.
That's probably the end goal, Kounde or De Ligt next summer.
