3 RBs, 6 CBs and no LB seem to raise a lot of eyebrows and rightly so, Bertrand and Targett are good enough LBs to play for England. TAA is the future, about time now Southgate ditches either Walker or Trippier.
Happy for Phillips and Ward Prowse, Grealish and Maddison are better than Mount for me.
Greenwood and Abraham are there because they play for big clubs, Kane and Ings are enough ST options, Rashford can play there too.
My ideal 23 man squad would be
GKs - 3 GKs
RBs - TAA, Walker
CBs - Gomez, Dier, Dunk,
LBs - Bertrand, Targett
CM/DMs - Henderson, Winks, Ward Prowse, Rice, Phillips
AM/Wingers - Sancho, Grealish, Madison, Foden, Sterling, Rashford
STs - Kane, Ings
**Rice and Phillips can play both CB and DM roles**
