Jose Mourinho has his Chelsea side clicking at the top of the Premier League, but how much have they improved this season?

After Jose Mourinho missed out on clinching the Premier League and Champions League titles last season, much was made of his second season. After all, Chelsea were still coming off a lowly finish under Andre Villas-Boas and Roberto Di Matteo, as well being 14 points behind winners Manchester United in 2012-13 under Rafael Benitez.

Mourinho had work to do immediately, but it became clear that it would take time to get his side playing as he wanted it when Samuel Eto'o was signed as a stop-gap solution to their striking problems. Now with £100m spent on Filipe Luis, Cesc Fabregas, Diego Costa, Didier Drogba and Loic Remy, Chelsea have hit top gear.

With six wins and a draw from their first seven games of the season, Chelsea are the team to beat in the Premier League and remain hot favourites to lift the title once again after a blistering start to the campaign - but in which areas have the Blues improved in Mourinho's second season?

The stats above show how Chelsea are scoring more goals per game than last season despite having much fewer shots on goal - which is almost certainly down to the stunning start made by £32m striker Costa, who has hit nine goals in seven games to lead the goalscoring charts in the Premier League.

Additionally, Chelsea have been passing the ball far more than last season, which again is a direct correlation with their signing of Fabregas. The classy midfielder has racked up seven assists already this season, and his passing is a large reason for Chelsea creating better chances - albeit fewer - and improving passing, hence the reduction in crosses per game.

Yet Fabregas offers very little defensive stability, and Mourinho's finest team was built open Claude Makelele and Michael Essien offering great protection for the back four. The number of tackles made by Chelsea is up, but it hasn't helped them keep goals out - which is something Mourinho won't be happy with as they look to claim the Premier League crown.
