Yep. The players look tired and burnt out from Mourinho's style - Hazard, Costa, Matic, Ivanovic, Fabregas all looking bad, Costa apparently returned overweight to pre-season. Depth-wise, I'm kinda in between you two - yes, they have some depth and shitload of good young players, but
a) Jose doesn't really trust them, he plays his favourites instead(Ivanovic)
b) players like Ramires, Mikel, Remy are not really like for likes replacements and I guess they'd have to change formation a little bit
I think they have to stop trying to grind the results, fans are bored of it if they're not winning. And stop with off field shenanigans, again, it's pissing everybody off if they're not winning.
