I certainly think there are a couple of players being left out who could possibly make a difference ... at least if you base the team on statistical analysis of our Premier League results per starter !
In our 17 games, we have won 9, drawn 2 and lost 6, which means we have achieved 57% of the available points. So anyone who has a better percentage than that in the games they have started is a net contributor, and should be in the team. The ones that stand out (positively) are Alonso, Hudson-Odoi (admittedly only 2 games, so small sample), Barkley ... and the ones that stand out negatively (we do worse when they are starters) are Emerson, Kante, Pedro and Giroud.
Playing a 4-3-3, the starters, based on points won when they start, would be those names in blue bold. Players who are "net contributors" are shaded blue.
You could argue Kovacic in place of Jorginho, or Christensen ahead of Zouma, as they are both very close.
So our statistically best PL line up is :
Azpiliceuta ; Zouma ; Tomori ; Alonso
Barkley ; Jorginho ; Mount
Willian ; Abraham ; Hudson-Odoi
