Was just going through this thread again
The turn around has been incredible from Xhaka. The 22/23 version is like a player from an alternate dimension. Kudos to him and Arteta.
I have no doubts that Havertz is going to be capable of, at the very least, replicating what Xhaka provided offensively this term. Xhaka is a player who was converted into this role. Kai is a player who was chosen for this role. It's more in tune with his natural instincts - He'll thrive here.
