One game at a time, Chelsea's ability to get results puts them in the driving seat in the Premier League title race, even if Jose Mourinho does not admit it.
The Chelsea boss believes it is Manchester City who have the league most within their grasp, thanks to their two games in hand which if won, would see them leapfrog the Blues.
Yet at this stage every point won or lost counts, and not just by your own club.
A Chelsea player well aware of the teams around them is Nemanja Matic, who insists he isn't focusing on any other team, but was delighted to see Arsenal lose to Stoke at the weekend anyway.
Matic told Chelsea.com: 'Like we said before, we will play game by game, to win every game if it is possible and we don't look too much at other clubs, but for us it is good if our rivals lose some points and on Saturday Arsenal lost so that is good for us.'
The Serbian has yet to face the Gunners since joining in January, and will get his chance when the two teams face off later this month.
He has a unique chance to become a double league champion this season, with former club Benfica leading the Primeira Liga in Portugal while Chelsea top the Premier League.
The weekend's results meant Chelsea's lead over Arsenal was extended from one point to four points, slightly easing their own margin for error and pressure as a result - and may even see them go onto play more freely once the international break is over.
