Harry Kane returned to form as he struck a hat-trick to sink sorry Bournemouth.
The England international had scored just once for Spurs this season heading into the clash at the Vitality Stadium but showed his finishing touch had not deserted him as he scored three in the 5-1 mauling of Eddie Howe's side.
The hosts had raced into a 49-second lead thanks to Matt Ritchie's smart finish but a string of errors from goalkeeper Artur Boruc proved to be Bournemouth's undoing as Kane helped himself to a hat-trick, with Mousa Dembele and Erik Lamela also on the scoresheet.
Boruc, returning to the starting line-up after missing the 5-1 loss to Manchester City last week due to an injury in the warm-up, had a day to forget while Kane, who was courted by Howe during his tenure at Burnley, has the match-ball as a memento from what he will hope is the turning point of his season.
It started so promisingly for the hosts as they took the lead inside the first minute as a cross from Charlie Daniels evaded everyone in the middle, with Ritchie arriving at the back post to score.
Ritchie's early strike was cancelled out by Kane's equaliser from the penalty spot after he had been felled by Boruc.
Tottenham then took the lead as Danny Rose's speculative effort deflected fortuitously into the path of Dembele, who coolly finished past Boruc, picking up a knock in the process.
Boruc did well to prevent Toby Alderweireld scoring the third when he kept out his near-post header but the experienced Polish stopper's afternoon did not get any better as he was culpable for Tottenham's next goal on the half-hour mark.
Kane wriggled free on the left but could only hit a tame cross into the box. However Boruc failed to hold it and spilt the ball straight into the path of Lamela, who made no mistake.
Bournemouth were still creating chances of their own and were unlucky not to reduce the arrears just before the interval as Marc Pugh saw a scuffed effort cleared off the line by Alderweireld before King hit the inside of the post moments later.
Boruc almost produced another moment to forget shortly after half-time as he took his time in clearing the ball and Dembele charged down his kick, although thankfully for the goalkeeper it rebounded straight back to him.
He could do nothing to stop the fourth Spurs goal as Kane slid in to convert Eriksen's cross and put the result beyond doubt.
With Kane in search of his second Premier League hat-trick, the England striker came close with a rasping shot that Boruc turned behind - but the wait would only go on for a few more seconds.
The resulting corner was headed towards goal by Alderweireld and again Boruc could not hold on. Kane was on hand to score his third of the afternoon.
Ritchie was the chief goal-threat for the shell-shocked hosts and forced Lloris into action with a long-range strike before Eriksen's fine effort came back off the post for Spurs.
Kane had legitimate calls for a second penalty turned down by referee Roger East as he looked to capitalise on yet another Boruc spill, with the goalkeeper catching Kane's leg as he looked to recover.
The striker was taken off with little over five minutes remaining, to be replaced by Clinton Njie. He failed to open his Tottenham account due to a smart stop by Boruc.

Harry Kane: On any other afternoon Eriksen's sublime display would have meant he would walk any poll for star player. But Kane's hat-trick, coming after such a barren run for the England forward, just edges out his team-mate.
MOMENT OF THE MATCH
Artur Boruc: Hard to select which of the Polish goalkeeper's clangers deserve to be highlighted here but his first fumble proved costly, gifting Lamela Tottenham's third goal and taking the game away from the hosts.
VIEW FROM THE BENCH
Eddie Howe opted to recall Boruc after he was injured in the warm-up at Man City last week and he will be regretting that decision this evening. For Mauricio Pochettino, his decision to start Kane having rested the striker for the Europa League defeat at Anderlecht, was vindicated. Dembele was also impressive in a more advanced role.
MOAN OF THE MATCH
Bournemouth have drawn plenty of plaudits for their style of football since gaining promotion to the Premier League but even the very best sides would struggle for results with such a shaky goalkeeper.
WHO'S UP NEXT
Liverpool v Bournemouth (Carling Cup fourth round, Wednesday October 28).
Tottenham v Aston Villa (Premier League, Sunday November 2).
