Stats: Below average! Despite top spot, Chelsea still under-perform in these areas

Stamford Bridge Outside

Chelsea manager Jose Mourinho could be on the cusp of going through the season unbeaten but there are still areas to improve in his team.

Chelsea's resemblance to Arsenal's famous Invincibles team is perhaps not a comparison in tactics and formation but more in terms of the confidence each individual has in the effectiveness of the team unit.

For the Gunners, there were animals in many positions - from the unheralded and underrated Lauren, centre back rock Sol Campbell, invisible wall Gilberto Silva, through to the rampaging box-to-box midfielder Patrick Vieira, the close control of Dennis Bergkamp and killer instinct of Thierry Henry.

Animalistic is also an adjective frequently used to describe penalty-box predator Diego Costa. A man who will just as likely get himself booked in the spirit of tough competition as he would score a vital goal and a player who is seemingly tough to defend against - as his current Premier League record of a goal scored for every 65 minutes he is on the field is testament to.

Costa is as good at finishing inside the box as Francesc Fabregas is at creating goal-scoring opportunities just outside it. The Spaniard has been at the heart of Costa's prolificacy and has been supported well by Eden Hazard, with monstrous midfield shield Nemanja Matic providing great protection to Branislav Ivanovic, John Terry and Gary Cahill.

Despite the prowess of Chelsea, there are certain things they could be doing even better. When it comes to pass accumulation per match, Chelsea are streaks ahead of the average for the Premier League, however, as is demonstrated by the forward pass (passes toward opposition goal) and penalty area entry (passes destined for the opposition box) statistics, the Blues could be even more penetrative with their build-up play.

Jose Mourinho teams are typically renowned for their defensive stringency and, while they have one of the more superior records in the current edition of the Premier League (only Southampton have conceded fewer goals), Chelsea are guilty of committing more human errors that lead to an opponent gaining a shot on goal than the majority of the 20 teams participating in the top English division.

Once Mourinho is able to drill out these errors, the Blues should concede at a greater rate than one goal per game.
