Premier League leaders Chelsea visit in-form Arsenal on Sunday afternoon.
The home side have won eight consecutive Premier League games and have claimed more points than any other team in the top-flight in 2015.
However, Chelsea presents the toughest test possible for the Gunners winning run, as Jose Mourinho drives his bus to north London.
The Portuguese boss likes to be pragmatic in big games like Sunday’s and it has worked pretty well for the former-Real Madrid boss in his glorious career so far.
If the Blues claim a victory in north London, then they will need just one more victory to claim the Premier League title this season.
Mourinho is a serial collector of silverware. Everywhere he has gone he has won trophies. He is the closest thing to a guarantee of winning as you can get when it comes to bosses.
The visitors have a slight hoodoo over the Gunners, as the side from north London have claimed just two wins in the last 12 meetings between the two teams.
Gunners boss Arsene Wenger has also struggled against Mourinho and in 13 meetings the Frenchman has never got the better of his Chelsea counterpart.
The veteran Arsenal boss will be looking to end that record this weekend.
If the Gunners do win then it will leave them seven points behind the Blues in the race for the Premier League title.
However, even if that happened it looks like Arsenal will just be delaying Mourinho’s men’s run to claiming the Premier League trophy.
Can Chelsea end Arsenal’s winning run?
