The Lilywhites moved seven points behind Leicester City once more.
The pressure was heaped on Spurs straight from kickoff after the Foxes beat Sunderland 2-0 earlier in the day to establish a 10-point gap, but goals from Dele Alli, Toby Alderweireld and Erik Lamela won the points for Mauricio Pochettino's side in a ruthless second-half showing - all three coming in the final 20 minutes.
Much of Tottenham's success this season has stemmed from Pochettino's gruelling physical demands, and Lamela, in particular, embodied what his manager looks for with a superb all-round showing in North London.
The 24-year-old is arguably the most improved player under the Argentine, and it is clear that Pochettino has helped him develop an ugly aspect of his game - some steel to match the silk he brought with him from Roma in 2013.
This is reflected in the statistics, with Lamela's goal and assist looking rather meagre in comparison to the off-the-ball work that he put in on Sunday.

With 10, Lamela won more duels than any other player on the pitch - including Mousa Dembele, who had eight - and he was also head and shoulders above the rest in terms of tackles, making seven and winning five of them.
He also managed seven ball recoveries - as many as Eric Dier - and won possession back in the middle of the park on five occasions. He will get credit for his goal and assist, and rightly so, but it is clear that there was so much more to his contribution against the Red Devils and Tottenham fans will be delighted - despite him also missing a first-half sitter.
He is now a far cry from the £25 million flop he looked like for so much of his Spurs career.
