Tottenham manager Antonio Conte says Saturday's emphatic win at Leeds "has to be a starting point" for his side as they inflicted another damaging blow to Leeds' hopes of staving off Premier League relegation.
Spurs broke the deadlock after just ten minutes when Ryan Sessegnon broke clear down the left and delivered a perfectly weighted cross for Matt Doherty to sweep home.
Dejan Kulusevski drilled in the visitors' second before Harry Kane's composed finish made it 3-0 on the half-hour mark.
Son Heung-min compounded Leeds' misery in the second half when he latched on to Kane's ball over the top of the home defence and beat Illan Meslier with a smart finish.
"I have seen a desire and a will to fight in every moment of the game," said Conte, who had questioned his future following Wednesday's defeat by Burnley.
The Italian told BBC Match of the Day: "They fought during the game and it was good for me to see this.
"If we want to be competitive, try to improve and build something important, it is not enough to play football and enjoy football. You have to win, and to win you need to match good football with a great desire."
"We had to put great desire and determination into every game from the start until the end, and today we saw this. My teams are not soft. My teams need to be strong."
Robin Koch and Raphinha struck the woodwork for Leeds and Stuart Dallas should have scored a consolation prior to Spurs' fourth, but the hosts rarely looked capable of forging a route back into the game as Spurs continued to carve out opportunities on the counter-attack.
The result lifts Tottenham to within five points of fourth-placed Manchester United, while Leeds are now just two points above the bottom three.
Bielsa insisted prior to Saturday's game that he had no intention of walking out on the club, despite being "very worried" about his team's poor recent form.
This latest defeat - which was almost embarrassingly one-sided in the first half - will do little to ease those concerns.
Tottenham carved Leeds open at will in the early stages, their 3-0 lead after just 27 minutes a fair representation of their dominance.
It could have been 4-0 just after the half-hour mark, but Sessegnon fired straight at Meslier's legs from a tight angle.
Boos rang out around Elland Road at half-time, although the home fans continued to sing in support of their team in the second half - with the game as good as lost.
Leeds, predictably, had chances of their own, although the majority came after they had gone 3-0 down. Koch rattled the post with a side-footed effort in the first half, while Luke Ayling sent a header narrowly wide of the top corner as the hosts pushed for a goal back before the break.
Dallas should have got his team on the scoresheet after rounding Hugo Lloris, but Ben Davies managed to get back in time to block the Northern Irishman's shot. Raphinha was also denied by the woodwork from a trademark free-kick.
Bielsa's side have now conceded 60 league goals this season - five more than bottom club Norwich - and 20 in February alone. They are only the second team in Premier League history to ship three or more goals in five consecutive matches.
The Argentine says abandoning Leeds' all-action style in favour of a more pragmatic approach is not an option, but it is hard to see the club arresting their dreadful form without a change of system.
Conte cast doubt on his Spurs future in an emotional interview following Wednesday's defeat at lowly Burnley, but the Italian - like his opposite number Bielsa - reiterated his commitment to the club before Saturday's encounter, insisting he retains the full support of chairman Daniel Levy.
Despite losing four of their previous five league matches prior to the trip to Elland Road, his team remain firmly in the mix for a top-four finish, with games in hand on fourth-placed Manchester United and West Ham, in sixth.
Leeds applied pressure late in the first half and were perhaps unfortunate not to make the scoresheet in the second, but the visitors never looked like leaving West Yorkshire with anything other than three points once Kulusevski had doubled their early advantage.
The only disappointment from Conte's perspective will be that they failed to add further gloss to the scoreline after taking such an early three-goal lead.
Son's late strike means the South Korean and Kane have combined more than any other pair in Premier League history, moving clear of former Chelsea duo Didier Drogba and Frank Lampard on 37 goals.
With games against the Red Devils and the Hammers coming up in mid-March, the next few weeks could go a long way to defining Spurs' and Conte's season.
