5-2 v Southampton FC - 20 September 2020 - Away

Son Heung-min said it was "incredible" to score four goals as Tottenham secured their first Premier League win of the season by coming from behind to thrash Southampton.

The South Korea international combined with Harry Kane for all four of his goals as Spurs took control after Danny Ings' fine finish from a tight angle had given Southampton a first-half lead.

"It's incredible to score four goals in the Premier League, it's a big honour," said Son.

"I wouldn't have scored four goals without this guy (Kane). He's amazing. Four assists, he deserved the man of the match today.

"We've been working for five seasons now together, we know what we like."

Son's first came on the stroke of half-time when he raced on to Kane's pass before driving across Alex McCarthy and into the back of the net.

The pair opened up Southampton again as Spurs took the lead soon after the restart, Kane sending Son through one-on-one and the forward making no mistake.

The hosts struggled to deal with Son's superbly timed runs behind the defence and he duly got his third, racing on to Kane's clipped pass before slotting in.

Kane then provided his fourth assist of the day with a brilliant cross for Son, who coolly chipped McCarthy, before Kane got in on the scoring himself when he stabbed in from close range after Erik Lamela's shot had been pushed on to the post.

Ings converted a penalty in stoppage time but it was scant consolation as Southampton slumped to their third consecutive defeat in all competitions.

This was a much-needed win for Tottenham after a difficult start to the season in which they were beaten by Everton on the opening day before scraping past Bulgarian side Lokomotiv Plovdiv in Europa League qualifying in midweek.

A significant reason for their defeat to the Toffees was their lack of creativity in midfield - with Dele Alli paying the price in that game for a disappointing display by being taken off at half-time.

Left out of the midweek Europa League tie, Alli was again omitted from the side for the trip to St Mary's, with Jose Mourinho saying his absence was down to having "too many players" in certain positions.

For a long time in this game, Mourinho's bold move looked destined to be the talking point as Tottenham sorely lacked creativity in midfield.

Aside from a couple of disallowed goals for Kane, the visitors barely troubled the Southampton defence and even when they did manage to score right before the half-time whistle it came from Tottenham's only shot and only touch in Southampton's box in the entire first half.

But after the break, Son and Kane took centre stage, taking advantaging of Southampton's high line and slow defence as they demonstrated an understanding that seemed almost telepathic at times.

Kane assisted just two league goals in the entirety of last season but almost every pass he provided in the second half of this game was to set up a Son goal as he became the first player in Premier League history to assist a single team-mate four times in the same match.

With the return of Gareth Bale, Tottenham have the potential for a front three that could rival the very best in the world.

A seven game unbeaten run at the end of last season gave Southampton fans plenty of reasons to be optimistic that their side could challenge further up the table this term.

Things have so far not gone to plan. The Saints have been beaten in all three of their games this season, losing to Crystal Palace in their Premier League opener before they were knocked out of the League Cup by Championship side Brentford.

Ings, who scored 22 league goals last season, has been linked with a move to Tottenham in this transfer window and he showed why it is crucial that the Saints keep a hold of him.

His first goal in this game was a superbly taken finish and he was a constant thorn in the Spurs side in a first half Southampton had the better of as he pressured defenders in possession and linked up play in attack.

But Southampton cannot rely on Ings to win games on his own and will need to show better in defence than they did in the second half as time and again they failed to pick up the runs by Son.

"The way we defended was a disaster," conceded Saints boss Ralph Hasenhuttl after the game.

"That is something we will have to speak about because it was stupid. In the end it was a deserved defeat."

Spurs manager Jose Mourinho to BBC Sport: "We didn't start bad at all. In the first 10 or 15 minutes we were good. After that we lost control.

"In the centre of our defensive area, we were a bit sloppy. We lost some duels. They got the ball behind us too easy. I was on the bench and thinking I would be happy to get in at 1-0.

"The goal gave us a different position in the game. In the second half, Harry Kane killed the game, the way he connected the game, the way he was dropping, he allowed Son Heung-min into attacking spaces. His performance was amazing.

"In the second half we were too good for them."
