Yes a few cracks were seen against the incredible organisation of Inter Milan and the occasional lapse against "lesser" sides seemed to happen more often but having a 6 and 0 tally against your biggest rivals (Man Utd, Arsenal and Liverpool) means that the evidence of terminal decline is still not apparent.
With the continued development of Man City into a credible side I think this season will be similar to last in that one team will certainly not run away with the title. Many games will be lost and a points tally in the mid 80's should seal the deal. In my mind Man City are the biggest danger to Chelsea's ambitions of retaining the title should the incredible talent on offer merge into a decent unit as opposed to a collection of individuals.
What I think will be trully interesting this season is to see what side Carlo Ancelotti will select both with regards to tactics and personnel. Last year we saw a number of different systems used from the the 4-4-2 diamond, orthodox 4-3-3, 4-2-3-1 and 4-3-2-1. All of those formations used different variations on players and had the same players playing a number of different roles.
For example, at the start of the season, Lampard was deployed at the "tip" of the diamond with Deco playing at the "base". This was an interesting deviation for Chelsea who have been striving for another "Makelele" for years. This system, however, proved to be slightly wrong as Lampard was simply not creative enough and Deco did not have the presence to be effective in the creative holding role against "top top" sides. As such the team moved to a more orthodox 4-3-3 with Lampard having a stunning second half of to the season. So what options are available for this year?
An Orthodox 4-3-3
