Arsene Wenger maintains Arsenal must stay focused on producing "outstanding performances" for the rest of the campaign rather than worry about what might be going on with their rivals.
The Gunners have so far failed to mount a serious challenge for the Barclays Premier League title, and are currently outside the top four as they prepare for Monday night's FA Cup fourth-round replay against Cardiff at Emirates Stadium.
"I believe [we should] focus on our way to be successful and not too much on the others," said the Arsenal manager.
"We need outstanding performances until the end of the season and the only way to achieve that is by focusing on our performances.
"If Chelsea gain points Aston Villa will drop, it is all linked together, but if we are consistent we will be there."
Chelsea were swift to act following a poor run of form under Luiz Felipe Scolari, axing the World Cup-winning coach and replacing him with Dutchman Guus Hiddink, albeit only until the end of the season.
Wenger admitted the decision by Chelsea to remove Scolari, who also had great success in charge of Portugal, from a position he only took up in the summer had come as a "massive surprise".
"Your reputation helps you to get you a job and to survive a bit longer than usual, but I do not want to interfere with that," Wenger reflected.
"I am sad when a manager loses his job, but it is very difficult to assess the situation from outside."
