Arsenal boss Arsene Wenger has stressed his players must keep their heads in the race to secure Champions League football after they moved up to third place in the Barclays Premier League with a 1-0 win at Everton.
The Gunners' sixth consecutive top-flight victory saw them leapfrog Tottenham, who drew 1-1 with Stoke.
A top-four finish seemed a tall order for Wenger's men at the start of February, yet they are now a point clear of their north London rivals and six ahead of fifth-placed Chelsea - defeated 2-1 at Manchester City - with nine games left to play.
"We want to keep going and we must not think now that the most difficult thing is done," the Frenchman said.
"Probably the most difficult thing still remains to do, and to achieve it it is important we keep humility, focus and fight for each other - that is what we had to do here (against Everton)."
Everton continued to press after the break, but Arsenal held out for the three points and Wenger said: "We were resilient, focused and showed a great desire to defend - our defence played very well."
