Agree, Grealish has not been impressive at all this year, seems Pep trusts Doku more to make an impact whenever he needs a sub LW to come on. Eze played quite well yesterday so he has an upper hand over Gordon and Grealish.
Bowen did not play well yesterday. Cole Palmer may get picked over him and since Cole Palmer can also be AM, that would be an attractive option for GS to consider over Bowen.
For now, Gordon, Maddison and Grealish are at high risk being left out and only one of those may get picked. The main reason is that Foden will be either LW or AM, so if Southgate needs 4 players to cover that 2 positions, that would be Bellingham, Foden, Eze and only one of these 3 above.
