It's been a little over three months since the 2013-14 season kicked into action, and in that time we have been able to get a better idea for how well things will go for Jose Mourinho upon his Chelsea return.
Given his impact at Stamford Bridge during his inaugural spell in charge—winning back-to-back Premier League titles, among a host of other trophies—it was understandable that most Chelsea supporters would be expecting a similar outcome.
This is a different Premier League, however. It's one that has changed considerably in the 10 years since Roman Abramovich purchased the Blues, and with the money being spent on new recruits by their rivals, the level of competition has gone up a notch.
It's a also a very different Chelsea team that Jose Mourinho has inherited and one very different to the team he took to unprecedented success in 2006.
How do those teams match up against one another? Are Chelsea stronger now than the team that secured successive Premier League titles? Or are they weaker and in need of more inspiration from their leader?
Looking at some key areas in the make-up of the team, Bleacher Report investigates a little further.
