Agree he's a good player, City don't have any bad players, I just stated it is marginal whether he's better or worse than what we've already got so I wouldn't take him on that basis.
I reckon if you did a combined City/Arsenal 1st XI then Saliba and maybe Odegaard get in (not ahead of KDB though hence 'maybe' in the Foden role). Saka not so much this season (last season he'd have got in), Rice is terrific but Rodri is even better.
But if you did a combined Arsenal/Liverpool XI there'd be many more Arsenal players in that side.
