If we manage it correctly there is NO reason we cannot give it a fair crack.
Lets say Lloris,Walker,Verts,Rose,Kane,Eriksen,Mason,Chadli,Bentelab never kick a ball (or travel) in the EL until the knock out phase. And we rely on the rest of 'the squad' to see us through the group stage.
The knock out part of the EL does not start until lateish february (19th this year). By then the league cup will only have the final left, and we'll be at the quarter-final stage of the fa cup. So we could easily be knocked out of either of those cups by then or have very few games left to play in them. Also some of those players could also swerve a few league cup/fa cup games. When the EL knock-out starts just select from the whole squad.....basically thats 3 months of the season left, with nine (main) players with mainly just league miles on the clock.
Vorm,Vlad,Dier,Kaboul,Fazio,Davies,Yedlin,Paulinho,Stambouli,Townsend,Lamela,Dembele,Soldado,Ade,Fredericks,Pritchard,Veljkovic,Capoue,....Carroll,Holtby........this lot should be able to see us through the group stages??
