I've been assuming it's nailed on Partey's sticking round since Jorginho was clearly off and we won't have the appetite to bring in anyone on top of Zubimendi.
I can see the arguments from a technical continuity perspective but not when it comes to results.
Partey's two or three "brain snaps" at the end of our European campaign arguably cost us our first European Cup. It's not a factor of his decline, it's how he's been for years when the competitive pressure ratchets up. Couple that with Partey's apparent need for regular selection to stay sharp and I'd rather find an alternative via Merino, Rice and Skelly.
The capacity to fluently play something other than this 6–8–8 midfield is probably the tactical piece we're missing anyway.
