Tottenham manager Mauricio Pochettino likened Son Heung-min’s energy levels to “a battery” after his late strike beat Newcastle and moved them second in the Premier League.

The South Korean forward benefitted from a Martin Dubravka error with seven minutes left as his powerful 20-yard shot went under the Newcastle goalkeeper’s body.

“Sonny is like a battery that you have – you work, work, work until the battery is gone,” said Pochettino. “He is like this. He gives you everything and when he is exhausted he says he needs to rest. On the pitch he is always 100 per cent in every action.”

Newcastle were well organised and gritty throughout, with Fabian Schar’s acrobatic goalline clearance to deny Christian Eriksen in the second half epitomising their spirit.

Rafael Benitez’s side had chances of their own, with Salomon Rondon heading against the post with the score at 0-0 but their resistance was broken when substitute Fernando Llorente laid the ball off for Son to score a ninth goal in his past 10 Spurs appearances.

The win means Pochettino’s side set a Premier League record as they reached 29 matches in a row without a draw, eclipsing Bolton’s mark of 28 set in 2011.

Son and persistence win the day

Spurs’ lack of draws perhaps shows they refuse to settle and that has certainly been the case in recent weeks with late goals earning wins against Fulham, Watford and now Newcastle.

The snatching of such wins points to the kind of spirit Pochettino has needed from his players when faced with injuries to key names like Harry Kane and Dele Alli.

Perhaps no-one has stepped up more than Son.

His return from South Korea duty at the Asian Cup has proven key and just as fatigue looked to be setting in at Wembley, he found the space to win it.

It was the 14th goal he has been directly involved in during his past 10 Tottenham outings and ultimately moved his side above Manchester City – who play Arsenal on Sunday – and four points behind leaders Liverpool.

No-one had more shots than Son’s five but Llorente’s introduction from the bench on the hour was also pivotal as he served up the assist.

Spurs, with help from Dubravka, ultimately found an answer against a side who sat deep in a 5-4-1 formation and threatened in pockets on the break.

Given Lucas Moura headed wide from close range early on, Erik Lamela headed against the bar and Schar’s clearance from Eriksen, few could argue Spurs did not deserve three points.

Pochettino may not be happy that only four of their 21 shots hit the target but they got the job done for a third league win in a row.

Newcastle show promise in defeat

Newcastle, while defensive, looked confident in their tactics following Wednesday’s shock win over Manchester City.

Their wing-backs – DeAndre Yedlin and Matt Ritchie – tucked in to make a narrow back five and Spurs were repeatedly forced left.

Jan Vertonghen had delivered nine crosses by half-time, his highest mark in the Premier League, as Newcastle’s plans largely worked.

And with Rondon a presence up top they had chances of their own. He saw an effort blocked in the box before the break and perhaps should have opened the scoring after the interval when his guided header hit the post with Hugo Lloris beaten.

Ayoze Perez also warmed the hands of the Spurs keeper from long range in the second period as Newcastle showed pockets of threat for their 28% possession.

They could have been better on the ball for periods, but Benitez will look at the dogged displays of Schar and Jamaal Lascelles as positives, along with the general resistance his side offered.

January addition Antonio Barreca came off the bench for his debut late on, while record signing Miguel Almiron was ineligible while he awaits a visa.

If the new £20m forward brings the quality fans crave, gutsy displays like this will at least give him a solid platform from which to perform as they look to climb the table after a result which leaves them 15th.

Man of the match – Son Heung-min

Fernando turns provider – key stats

• Newcastle have lost their past eight visits to Wembley in all competitions since winning the 1955 FA Cup final against Manchester City – extending their record for worst ever losing run by a team at the stadium.
• Tottenham have lost just one of their past 27 home Premier League games in February (W19 D7).
• Newcastle have lost 13 of their past 14 Premier League games away to ‘big six’ teams (D1), since beating Tottenham 2-1 in December 2015.
• Fernando Llorente has been involved in seven goals in his past eight appearances for Tottenham in all competitions (five goals, two assists).
• Llorente provided assists in back to back league games for the first time since March 2008 for Athletic Bilbao.

The Llorente impact – what they said

Tottenham manager Mauricio Pochettino: “It was difficult to find space. We created some chances in the first and second half but the most important thing in the end is to keep pushing and it was a massive effort again in the second game consecutively. Once again I need to praise my players.

“Llorente, after Harry Kane’s injury, plays four games in a row and with three days’ recovery the normal thing is to rotate. It upsets me a little bit because the debate in England is difficult to understand. You have 24 players you need to use.”

Newcastle boss Rafael Benitez: “I think we did well in the first half and we had chances in the beginning of the second half. They were pushing hard, we were defending well and this goal we could’ve avoided.

“We have to give credit to Son because the shot was a good one and we hit the post in the second half, that was a big chance for us. You have to give credit to Tottenham because they have injuries. It was not easy for us.”

What’s next?

Tottenham welcome Leicester to Wembley on Sunday, 10 February (13:30 GMT), while Newcastle travel to Wolves a day later (20:00 GMT).
