A determined Spurs side showed their new-found resilience as they held out for a goalless draw at Chelsea.
Only the Spurs woodwork and a marvellous save by Paul Robinson prevented Jacques Santini's side from losing their unbeaten start to the league.
But the Blues failed to score the required goal and stay in second place in the Premiership.
Chelsea started as they meant to go on by gaining three corners in the first two minutes.
Then on four minutes Didier Drogba was put clean through by an Eidur Gudjohnsen pass, but Paul Robinson, quick and alert smothered the chance, the rebound fell to Tiago, who skied a 25-yarder well over the bar.
Soon after a nice right-wing cross by Paulo Ferreira fell right on to the six-yard line, but no Chelsea player was within striking distance.
Spurs, for their part had good possession in and around their area, but whenever the ball entered the final third, the moves broke down.
A brilliant last-ditch lunge by Ledley King denied Gudjohnsen the chance to get a strike on goal on 19 minutes, after Joe Cole's excellent run from midfield.
Gudjohnsen should have made amends on 23 minutes, but he headed wide from eight yards out after Cole once again set up the Icelandic striker with a chipped throughball.
Spurs made their first push on Chelsea's goal on 25 minutes when they managed their first corner, but it was cleared and the ball fell to Cole who ran 40 yards towards the Spurs goal before setting up Tiago, but the Portuguese midfielder scuffed his effort from just outside the penalty area.
Gudjohnsen did get a shot on target on 28 minutes, but it was weak and Robinson had the easy task of dropping on it.
Robinson, had to be at his England best to snuff out Drogba's shot from six yards on 33 minutes after Chelsea carved open the Spurs defence.
Jamie Rednapp's 25-yard effort which flew high and wide was Spurs' first effort on the Chelsea goal and it came in the 42nd minute.
Chelsea start the second half as the first with a corner within a minute, but once again Spurs showed their resilience in defence and cleared easily.
Drogba's audacious overhead kick almost produced dividends on 50 minutes, but no-one was close enough to prod the ball home.
He tried to make amends with a 25-yard free-kick, but the Ivory Coast striker hit Row Z on the South Stand instead on 55 minutes.
Spurs should have scored a minute later, but a miraculous save by Petr Cech from Robbie Keane's point-blank header saved the Blues' blushes.
John Terry 's diving flicked header from a Lampard corner on 58 minutes restored business as usual on the Sours rearguard, but it arrowed agonizingly wide.
In an attempt to break down Spurs, Blues coach Jose Mourinho brought on Damien Duff and Mateja Kezman on 66 minutes.
A free header by Ledley King from a Keane corner a minute later went haplessly wide.
Another overhead kick by Drogba after excellent set-up play by Duff and Gudjohnsen went aimlessly wide on 76 minutes.
Robinson saved Spurs with a fantastic reflex save on 80 minutes after Lampard's vicious free-kick caught out the Spurs defence.
Mourinho's last throw of the die was to put on Alexei Smertin for Wayne Bridge on 86 minutes, but not before Spurs got another let-off as Gudjohnsen's 20-yard volley rebounded off Robinson's right post.
Good defending by King denied Drogba from getting a shot off with three minutes remaining and the visitors held out through five minutes of added time to secure a hard-earned point.
