Lack of depth is gonna hurt Chelsea. Look for real early exits in the League and FA cups. Last year they did not play in Europe and it will catch up to them come February and March.
Chelsea isn't as thin as people think anymore.
CD -> have 5 (6 if you count Jake Clarke-Salter) in Azpilicueta, Luiz, Cahill, Christensen, and Rudiger
RWB -> Moses, Zappacosta
LWB -> Alonso, Kenedy/Rahman (once back from injury) -> one of the latter 2 likely to go on loan in Jan.
CMF -> Kante, Cesc, Bakayako, Drinkwater
AMF -> Hazard, Pedro, Willian, Musonda
ST -> Morata, Bats
More often than not will be playing 3-4-3, so have almost 2 per spot. Concern if injuries especially at Striker. Don't have cover in youth as all our top prospects there (Tammy Abraham and Ike Ugbo) are on loan.
If at the end of this month (5 more) we're exposed, then I'll be the first to rail at management for not "overspending" to ensure we have cover. However, I'll give them the benefit of the doubt until proven otherwise. Just like here at FSU, in Jimbo we trust, in Chelsea's management I trust.
EDIT: I know Manch, said come Feb/March we'll be short, but I think we'll find out much earlier than that if Chelsea is truly short on depth or if we'll be fine.
