thats a difficult one as there are many moving part to that question.
First what position does sterling play for Citeh? this is a matter of guardiola's preferred formation.
Second what position will grealish play for Citeh?
In theory guardiola plays a wide man "wide", the fully backs tuck in to allow attacking midfielders go find pockets so the wide men have to stay wide. Sterling is **** at this. Grealish is NOT a LW. england forced him out there. Grealish has played a nominal left side for villa but never tacked back or as a no 10.
I would say neither man fits the city mould all that well as a pure LW.
Can sterling pay anywhere else? City don't seem too pushed to put him RW or at CF.
Where might grealish play for citeh? Foden and silva have played false 9 and also as the attacking cm with de bruyne so will grealish play this? his lack of tracking would seem an issue to me. City laready had a massive issue with rodri not putting in the same efforts at no 6 so this is a recipe for a disastrous midfield imo.
Overall this certinyl looks like 2 men for one position but gaurdiola is more than capable of shoe horning players in. sterling is a worse no 9 than jesus for example and mahrez and torres have RW locked down between them.
Really this looks like 2 big egos for one position. I can't figure out anything else.
city squad
Ederson/Steffen
Walker/Cancelo Stones/Laporte Dias/Ake Zinchenko/Mendy
Rodri/Fernandinho
KDB/Gundogan Foden/Silva
Torres/Mahrez X/Jesus Sterling/Grealish
It seems to me that they are a kane shy of a full house
People then have the temerity to try to say city don't spend big.
Their second team is a drop off of quality but its a drop form 1st in the table to about 4th/5th.
