Assuming they stay fit, these are the players I think have a place in the squad:
GK - Henderson, Pickford, Pope
RB - Walker, James
CB - Maguire, Stones, Mings
LB - Shaw, Chilwell
CM/AM - Rice, Phillips, Foden, Mount
WF/CF - Kane, Calver-Lewin, Rashford, Sterling, Sancho
If they can get match fit, these players are in the squad:
Joe Gomez - CB
Jordan Henderson - CM
Jack Grealish - AM
Then I think you're filling the squad from this pool:
RB - TAA
CB - Keane, Coady
CM/AM - Ward-Prowse, Maddison, Oxlade-Chamberlain, Winks, Bellingham, Lingard, Saka
WF/CF - Ings, Watkins, Greenwood
Donkey - Dier
Assuming the 19 at the top stay fit, and the three with question marks over fitness get fit, that gives you a 22 man squad, with four spaces left.
If it were up to me, I'd be taking Lingard, Greenwood, Bellingham and Ward-Prowse to fill those extra slots. If TAA can find some proper form in the remainder of the season, he'd be in with a shout ahead of probably Bellingham.
