Tottenham Hotspur's come from behind twice to draw 2-2 at Chelsea to prolong a three-way all-London battle for the last two Champions League places.
The Iceland international Gylfi Sigurdsson shot low past Chelsea goalkeeper Petr Cech on 80 minutes to deny Chelsea a victory that would have effectively guaranteed the hosts a top four finish and Champions League football next season.
With two matches remaining, third-placed Chelsea remain in pole position on 69 points, followed by Arsenal (67) and Spurs (66).
Oscar opened the scoring for the hosts on 10 minutes, before Emmanuel Adebayor equalised for Spurs on 26 minutes.
Ramirez put Chelsea back in front before half-time but Adebayor's back-pass for Sigurdsson squared the scores and helped the Togo international earn the man of the match honours.
