I believe Guehi was England U21s Captain. I could be wrong. You're right about Zaha. Andersen could possibly do it.

I guess, ideally we'd like a tough midfielder who usually starts. We have Luka but he isn't really playing - and I'm not advocating that he should. Quite the opposite really.
Guehi has the advantage of playing every week plus experience of being a captain. I guess not all captains are the shouty types, but I totally understand what you mean. He seems quite reserved a lot of the time.
Frankly, I find a lot of our players too reserved, I'd like more fire from Olise, our 'strikers', Clyne, Eze, Schlupp, Mitchell. They just seems to not have that emotional connection with the club. I say seem - it just looks that way on the pitch to me.
