Willock was and is a great talent, initially he was the best of the kids when they nmxed with the first team, that was until Saka's breakthrough as an attacking force.
We shouldn't have sold him, especially for the pittance we got as I think he'd be perfect in this current Arteta system, easily being able to bench Xhaka for that free role.
I hope he doesn't start against us as he has that nick of being in the right place at the right time.
