Didier Drogba missed a stoppage-time penalty as Chelsea's Barclays Premier League winless run stretched to five matches with a 1-1 draw at Tottenham.
Heurelho Gomes looked to have gifted the champions the unlikeliest of victories when he clattered into Ramires having already handed Drogba an equaliser with a complete howler, but he redeemed himself by saving the latter's spot-kick.
Spurs had led through Roman Pavlyuchenko's ninth goal of the season and could easily have won but for their erratic goalkeeper.
It was a bright opening and Tottenham went ahead with their first real attack after 15 minutes. Jermain Defoe, who looked to be offside, fed Pavlyuchenko and the Russian striker superbly created space for himself and fired low past Petr Cech into the bottom corner.
Spurs continued to look dangerous with widemen Gareth Bale and Aaron Lennon threatening, but it was Chelsea that began creating the chances.
Salomon Kalou brought a good save out of Gomes with a 12-yard header and it was Kalou who went close again when his glancing header flashed wide.
Chelsea brought on Drogba at half-time in a bid to get back into the game, but it was Spurs who almost scored another when Defoe curled a low drive just wide.
Drogba began to threaten and tested Gomes with a drive from distance but after 69 minutes the Ivorian ended his drought by firing a fierce volley through the hands of Gomes, who would have been disappointed not to keep the shot out.
Lennon had the chance to regain Tottenham's lead but he could not control his low 18-yard drive and pulled it wide.
And Gomes' afternoon got even worse after his clumsy challenge on Ramires handed Chelsea an injury-time penalty, but the Brazilian made amends by stopping a poor Drogba penalty as it ended all-square.
