Chelsea has not lost against Arsenal in their last seven EPL games. Mourinho has never lost back-to-back home games.

No matter how bad Chelsea may be doing in the current Premier League season, looking at the stats sheet when they are about to face Arsenal can be good news. Both London sides are living two different realities, one is in fourth place and the other one is in 17th with only four points. 

In the last seven Premier League games between the two teams, Chelsea has been able to come out with at least a draw. After winning their first Champions League game during the week, Jose Mourinho feels condifent that things could go back to working his way after losing 3-1 to Everton on the road.

There is one thing Arsenal can brag aboutWenger was able to stop Mou's domination Also, ever since Mourinho has been a manager for the Blues, the team has never lost back-to-back home games. So far, they have played two games at home this season. They tied the first one with Swansea City 2-2, lost the second one against Crystal Palace by 1-2 and now look to beat Arsenal at Stamford Bridge. 

Striker Diego Costa, who just netted his first goal for Chelsea in the Champions League this week, feels that despite their situation in the EPL, the game against the Gunners could not have come at a better time. 

WATCH: Costa looks to recreate something like this

"There's nothing better than a game against Arsenal to win and fix this situation," Costa said. "If we win then we'll take a step forward in terms of confidence and points; we know about the importance of the game."

This season, Chelsea has scored only five goals in five games and received 12, to make it one of their worst starts in many years. Arsenal on the other side, has also only scored five but received only three. 

"We have to remain calm. We have enough quality to fix the situation," Costa added.

There are also a few points that are in favor of Arsenal, starting with their goalkeeper. Petr Cech is a former Blue and knows Mourinho's ways pretty well. The Czech goalkeeper has a total of 165 clean sheets and has not been beaten in his last three EPL games. The Walcott's 11 goals in his last 11 starts for Arsenal are significantly motivating for Arsene Wenger's side.

It will be a unique experience for the former Chelsea goalkeeper 

This game stands on its own

With the game being played at Stamford Bridge, Arsenal's hopes of coming out victorious look a bit remote. The team has not won in Chelsea's house since 2011. Once the ball starts rolling this Saturday, all these stats are left behind and everything may happen
