Will be really interesting who he picks, if you're just going off the leaders in the squad then I'd imagine Dier, Hojbjerg, Davies and Son are the stand out 4 as most others either feel to new to the squad or to young (Romero, Skipp) and then you'd probably argue he'll want someone who is likely to play every week so that probably rules Dier out but id say if Hojbjerg stays I could see him playing fairly regularly, at least until bentancur is back and I don't think it's beyond the realms of possibility Davies is used fairly regularly at LB or cB, but those two are very much players who could play on very week whereas you feel so is one who will play every week, and so assuming Ange wants a senior player, who's been at the club a while and who will start then I think Son is the only real option, but obviously Ange may have a completely different set of criteria i.e he doesn't actually care if his captain starts most weeks or is willing to give it to someone like Maddison despite him being so new to the squad.
