Arsenal boss Arsene Wenger played down suggestions the Premiership title was heading to Highbury despite his side's 2-1 away win over Chelsea.
The Gunners are seven points clear at the top of the Premiership - after closest rivals Manchester United could only draw 1-1 with Leeds.
Wenger told BBC Sport: "The seven-point difference is not enough with a three-point system.
"It's not a two horse race at all because Chelsea are still in it."
Goals from Patrick Vieira and Edu gave Arsenal the three points but the leaders lacked the outright creativity seen in recent weeks.
Wenger said: "We fought it out. At 2-1 I felt we lost our fluency a bit but overall we have shown another aspect of the talent of this team which is very positive.
"It will certainly have an importance because against your direct opponents you have got to take the points.
"We have done that today, but we will see. At the end of the season it will be a significant victory.
"Last year Manchester United had a fantastic run, and we didn't slip up as many people said - but we just want to keep going.
"Having an unbeaten run is not a problem though - the only problem in football is not to win the games. When you win the games you cannot complain.
"I don't understand how an unbeaten run can be a problem but everyone thinks differently."
