Rabiot is a must starter every game of the season aslong as he keeps this up (see his pass to Kostic past game). So he is defenitely a given over Locatelli. Locatelli is sound all around mid, but yeah I wouldnt reward this low effort play either, but we dont have much options. Paredes is NOT an option for me.
So I am waiting for Pogba to come back, to sideline Locatelli, not in role, but quality options. Then we can start Fagioli, the only viable other option as regista, with the two frenchies.
Because I dont really consider Paredes, Mckennie or Miretti viable long term starters for different reasons (Miretti is AM, not really regista).
So if your solution is simply Paredes, then no I'm not with that, thats just passing the buck on a worst option IMO, one thats days are numbered here. So I rather keep trying with a player thats ours and hope he improves.
