The gap between the Gunners and Manchester City has reduced to four points, but the latter has a game in hand.
After blowing a 2-0 lead against West Ham United, Arsenal manager Mikel Arteta has stressed that his players need killer instincts.
Despite taking the lead on goals scored by Gabriel Jesus and Martin Odegaard, the Gunners allowed the Hammers to fight back and ended up sharing the points in a 2-2 draw.
Arteta said Arsenal have to blame themselves for failing to register what had been a routine London derby against West Ham.
"We have to blame ourselves for how we defended those two goals in our boxes," Arteta said.
"We need to have that ruthless mindset to go and kill a team. When a team is there for the taking, we have to kill the team. And when you don't do that in the Premier League, at some point it's going to turn around.
"You have to fight and earn the right to play, but when we need it, you need to have more composure."

PREMIER LEAGUE Arsenal's title dream hangs by thread after draw at West Ham
The Gunners surrendered their lead twice to allow the Hammers to fight back and earn a point.
The Spaniard, however, ruled out fatigue as a factor that affected their performance at the London Stadium.
"Fatigue-wise? No. What we produced in the first and second half against Liverpool was similar and today we put a higher input in the second half than we did in the first half," he said.
"We were slower in everything that we did. I don't think the team is fatigued or looked fatigued. The best way to do it is convince them how good they are and do what they have to do.

WHAT'S BUZZIN 'I blame Arteta' - Reactions as Arsenal fans give up after major slip in title race
Arsenal threw away a 2-goal lead for a second consecutive match in the Premier League.
"I would say 'yes' if I see a team playing with [gestures nothing]. When I see a team playing with that flow [at the start of the game], that's not pressure. At 2-0, we were not under pressure. We just didn't do what the game required in that moment."
Although Arsenal – who also had Bukayo Saka miss a penalty - are now unbeaten in nine Premier League games since a 3-1 home loss to City, the dropped points only complicate their chances of winning the title.
