This is true, I hope you're right and we get there. It's also true that when the bigger games roll around we'll see a team made up of more or less what Ange will see as our strongest 11. I think a conversation around what that team will be is worth having.
Starting yes, but Ange likes subs for "high energy" roles
Honestly the back 5 is pretty set, with Dragusin being the obvious rotation/cover
Fully fit, it it's current version (unless incoming), Front line is similar -> Son, Richi, Johnson, with Werner/Deki as options
Midfield is where Ange needs to work -> Maddison, Bergvall, Bentancur, Sarr, Bissouma, Gray, maybe one of Skipp, PEH, GLC
