Arsene Wenger insists Arsenal can still win the title despite the 2-1 loss to Chelsea at Stamford Bridge.
The Blues came from behind thanks to a brace from Didier Drogba, after Bacary Sagna had scored the opener.
Arsenal have not won in the league for five matches, their worst run of form for nine years.
But Wenger, whose side now lie six points behind leaders Manchester United, said his side will not give up.
"We will fight until the end and we are not worried about the future but are disappointed now obviously," Wenger said.
"Today we were unlucky and I thought we played well. We were 1-0 up and were unlucky with their first goal which I thought was really offside.
"Anelka came on for them, and they decided to play long ball, which put us under a lot of pressure and that was the only way they could trouble us. In the end we lost the game.
"It is disappointing because we gave everything but now the priority has to be the next game."
The Blues' comeback was triggered by Avram Grant bringing on Nicolas Anelka and Juliano Belletti.
Grant said his side deserved victory after the amount of chances they carved out.
"I think we play good from the first minute, against a very good team.
"We had some good chances to score, again the other team scores against us from a corner, but we won the game.
"I don't know who criticises the substitutions. I know with substitutions sometimes you succeed sometimes you don't. Today it succeeded.
"Yes, [Anelka] caused them problems. But even before with Didier we created chances, but we didn't score."
Second-placed Chelsea clash with United at Stamford Bridge on April 26th in a potential title decider.
