The Italian manager would have thought his eight league games without a defeat was gone, but his decision to bring on want-away Dutch forward Steven Bergwijn got him out of jail.
With that extraordinary moment of magic from Bergwijn to seal victory against Leicester, Spurs not only have three points more and have jumped over rivals Arsenal into fifth place, but they look forward to taking on Chelsea with renewed energy and and an unbeaten run to protect.
Thomas Tuchel has given his players a little break after a hard-fought 1-1 draw at Brighton, and with the battle lines drawn here are five reasons why Spurs will feel the European Champions are there for the taking.
Tottenham have a better league record since Antonio Conte took over
Tottenham have jumped from mid-table, and are genuinely in the fight for a top four finish.
Since the Antonio Conte was appointed in N17, Chelsea have only managed two wins in their last nine games.
The pressure is on Tuchel, who has now gone from challenging for the league to now hoping to finish in a Champions League spot.
Former Chelsea boss Conte knows all about the pressure at Stamford Bridge, and will set up his team to go out and inflict more damage.
Tottenham will be look to avoid three defeats on the spin against Chelsea
Spurs have already lost twice to Chelsea, and will be mentally ready for the train that will hit them in south-west London.
Thomas Tuchel beat Pep Guardiola three times on the spin and will have to produce such level of dominance to crash Tottenham’s momentum and take all three points.
Given that Tottenham are more focused on the league and securing Champions League football, they will see this game as the perfect opportunity to make up for the defeats in the Carabao Cup.
Kane looking sharp again while Lukaku is still struggling to shake off that interview
Tottenham might have lost Son Heung-Min, who is not expected back until early February, but Harry Kane is beginning to look sharp both on and off the ball again.
His goal against Leicester was his fifth in the Premier League, and was the first time he has scored and assisted in a game this season.
Given he made his worst start to a Premier League, partly down to a failed move to Manchester City, the England captain is desperate for European football and it’s beginning to show in his performances.
On the contrary, Chelsea’s Romelu Lukaku looks like his confidence is shot to pieces and is now a pale shadow of the fearsome striker who fired Inter Milan to their first league title in over a decade.
He only has one goal to show for in the last five league games.
Tottenham have momentum
Tottenham will travel to Stamford Bridge, basking in one of the iconic moments in Premier League history.
The come-from-behind win against Leicester was similar to what Manchester City experienced against QPR, even if Spurs were not gunning for the Premier League title.
While Chelsea went into the game, having surrendered a lead against Brighton, with only two days to prepare.
Momentum, psychology and timing often define key games like these ones and they all point to Tottenham peaking at the right time.
Discomfort, chaos and players running down their contract at Chelsea
Chelsea are going through somewhat of a mini-crisis with results plummeting and contract issues continue to dominate headlines every week.
Antonio Rudiger, Andreas Christensen and César Azpilicueta all have their futures up in the air, and a couple of them will be thinking of other clubs at the moment.
Chelsea is a club where failure is almost devastating, and at this point every club coming to Stamford Bridge can small blood and wants to take advantage.
