When Roberto Di Matteo took over last season at Stamford Bridge, Chelsea were using primarily a 4-2-3-1 shape. Di Matteo didn't rock the boat, instead opting to continue using that approach for the remainder of the season. Di Matteo was then rewarded for doing so well with the 4-2-3-1 with a two year contract to manage one of the largest clubs on the planet. The buying began, and most fans immediately started plugging Chelsea's newest acquisitions into the 4-2-3-1. As we finished the season in that formation, this makes some sense. At some point though this starts to become a little unfair to Di Matteo, as it assumes that he's either unable or unwilling to alter the tactics we used last year.
