I agree regarding the squad, we have got decent options in reserve. Soldado, ade, Townsend, paulinho, stambouli, Dier, vorm,Yedlin and Davies are all pretty good back ups, I've not even included capoue, Kaboul and vlad and prob missed out 1 or 2 others.
I've always thought we've rotated in a poor way before, instead of changing 8/9 players we should be rotating 2, at the most 3 each time, that way the core of the side stays the same and hopefully performances are more stable. It's also why I think no one rates our squad, because all the fringe players are thrown in together having not played much together and without the aid of playing alongside some of the best players to help them through. Look at Dembele for example, wasn't pulling up trees in the cup teams but dropped in to the first team and he's almost a regular now.
