Arsenal boss Arsene Wenger admits his side have to focus on making it to next season's Champions League rather than fighting for the title.
The Gunners lost a golden opportunity to move closer to leaders Leicester City as they could only manage a draw at home against Crystal Palace.
With five games to go, they are 13 points from the Foxes with West Bromwich Albion next at the Emirates on Thursday night.
"It is very difficult, we had a lot of possession but did not make enough of it," Wenger told BBC Sport.
"We lacked a change of pace, sharpness, they defended well. We put a lot of effort in but came out with a frustrating result. It is hard to accept, the competition goes on and we focus on the next one.
"I don't know how it works mathematically but we are too disappointed to think about the league, we have to think about the Champions League and fight to be in the Champions League.
"We have another home game on Thursday night and had to prepare for that.
"On their goal, it did not look unstoppable, maybe the shot surprised him, but we maybe should have stopped the shot. It is difficult to blame individuals."
