Aaron Lennon's last-gasp strike against Birmingham made it four wins in four in the Barclays Premier League on Saturday.
Only seconds remained when Stephen Carr lost possession to Tom Huddlestone on the half-way line, allowing Roman Pavlyuchenko to cross and Lennon to cut inside two defenders, compose himself and fire low into the corner.
The timing of the goal might have been harsh on the Blues but victory was no less than we deserved after creating chance after chance, only to see the visitors equalise within minutes of us finally taking the lead.
That equaliser looked to have deflated everyone inside White Hart Lane but thankfully Lennon was there to maintain our 100 per cent winning start to the season.
Harry Redknapp made seven changes to the side that beat Doncaster in midweek with Ledley King, Benoit Assou-Ekotto, Lennon, Wilson Palacios, Luka Modric, Robbie Keane and Jermain Defoe all back.
Birmingham set up in a 4-5-1 formation but looked to have attacking intent in the opening exchanges as James McFadden and Sebastien Larsson tried to get up to support Garry O'Connor.
However, the five-man midfield was soon pushed back by wave after wave of attack and the second half of the period was like a chess game as we looked to find a way through.
The opening exchanges were frantic and Joe Hart was in action after seven minutes, palming out Lennon's low drive from Luka Modric's cross. Jermain Defoe then almost got a toe to Huddlestone's cross-shot before accidently getting in the way of Robbie Keane's volley.
The threat came from both flanks and Lennon was central to the next action. First, a shot on 18 minutes that forced a routine save from Hart, then he was on the end of Modric's cross and fired past Hart only to see the returning Spurs Stephen Carr to hack off the line.
City, who had seen O'Connor and Larsson have tame efforts at goal, then drew a gasp from the crowd as Larsson got goalside of Sebastien Bassong and fired inches wide.
That only prompted another Spurs attack and our best chance yet as Huddlestone picked out Defoe's run centrally and sent the striker clean through - unusually, he didn't get hold of his effort and dragged it wide.
That chance was on 23 minutes and appeared to prompt the visitors into dropping slightly deeper, so although we dictated possession, chances were few and far between, the best when Modric curled just wide from the edge of the box.
Harry was forced into a change at half-time as King left the action with a groin injury to be replaced by Alan Hutton, Vedran Corluka switching to centre-back.
Lee Carsley headed wide City's best chance two minutes into the half and then another injury blow as Modric went over awkwardly from Lee Bowyer's challenge and limped off. Peter Crouch came on for Modric and went up front alongside Defoe, Keane pushed out wide left.
After a scare when McFadden went over in the box on 57 minutes we put together a spell of pressure that eventually led to the opening goal.
Crouch's header was tipped around the post by Hart, Franck Queudrue headed to safety when Crouch looked to have presented Keane with an open goal, Defoe volleyed just over, Crouch headed against the crossbar and then held his head in disbelief as Carsley nodded another header off the line.
Crouch was the target again from Lennon's excellent cross and this time his headed struck Stuart Parnaby on the back of the head, the defender didn't look like he knew too much about it.
It was eventually fourth-time lucky for Crouch as the England forward rose majestically at the far post to meet Huddlestone's free-kick and loop a header over Hart and into the far post. Mayhem at the Lane, 72 minutes on the clock.
But the joy didn't last long - in fact, just three minutes. O'Connor crossed from the right corner of the penalty area, Hutton, Carlo Cudicini and Christian Benitez went in for it together, the ball squirmed out to Bowyer who had the easiest of tap-ins.
That goal hit hard and Birmingham created the next chance, O'Connor dragging a good chance wide from six yards.
It looked like what would have been a disappointing draw until Lennon drilled home the winner in the fourth minute of injury time.
