Clint Dempsey struck two minutes into injury time for Tottenham as they snatched a dramatic late draw against Manchester United at White Hart Lane.
Former Arsenal striker Robin van Persie had put United on course for a win when he scored his sixth goal against Spurs in the 25th minute.
But after a sustained period of pressure late in the game, Dempsey delivered Andre Villas-Boas' men a thrilling equaliser with less than 60 seconds of the match remaining.
The American, who had missed a gilt-edged chance earlier in the second half, got on the end of Aaron Lennon's pull-back and slotted home after David De Gea's weak punch.
The draw means United are now just five points ahead of Manchester City at the top of the table after Roberto Mancini's men after their win over Fulham on Saturday.
In Sunday's other game, Chelsea held off a spirited second-half fightback from Arsenal to triumph 2-1 at Stamford Bridge and give boss Rafael Benitez the rare pleasure of a home victory.
The Blues were dominant in the opening 45 minutes and were two goals to the good at the break courtesy of Juan Mata's early opener and a Frank Lampard penalty soon after.
But the Gunners were transformed after the interval and reduced the deficit through Theo Walcott before the hour mark.
They could not find a leveller, though as Chelsea held out to avoid a repeat of their midweek misery when they blew a 2-0 lead against Southampton.
