What we learned as Spurs beat Arsenal in Hong Kong

Tottenham Hotspur beat Arsenal in the first north London derby outside of the UK thanks to Pape Matar Sarr's excellent long-range chip.

The match, which was played in front of a stadium-record crowd of 49,975, gave a glimpse into what both sets of supporters can expect from their sides this season.

Sarr lobbed the ball over David Raya from near the halfway line in the 45th minute after Spurs won the ball back in midfield.

BBC Sport looks at what we learned from a rare pre-season meeting of these rivals.

Arsenal are known for their threat from set-pieces, scoring from 15 last season, with coach Nicolas Jover one of the most recognisable members of backroom staff in the Premier League.

After Arsenal won their first corner of the match, five players lined up along the 18-yard line - a sign they have been working on some new routines after their goals from corners dropped off towards the end of last season.

However, the Gunners also conceded from 14 set-pieces last season and Tottenham had opportunities to score from their own corners.

Pedro Porro and Mohammed Kudus both hit the post directly from corners, with one of the deliveries somehow staying out of the net after Richarlison attempted to put the rebound in from close range but instead helped it over the bar.

Spurs looked organised defensively when defending set-pieces, and throughout open play, with manager Thomas Frank looking to get his ideas over to his new team before the start of the Premier League season.

There has been a real difference in Arsenal's style and how they have approached games on their pre-season tour of Singapore and Hong Kong.

The Gunners scored 17 fewer goals than Liverpool last season and finished 10 points behind the champions in second place.

They struggled to break down teams that defended in low blocks, but against Spurs - and throughout pre-season - Mikel Arteta's side have got the ball forward a lot quicker than they did last season.

Goalkeeper David Raya is kicking the ball long as much as he is playing it short.

Arsenal also seem to be shooting more - they registered 23 shots against AC Milan, 15 against Newcastle and, despite losing, had 16 shots against Tottenham.

Arteta is clearly hoping that getting the ball forward quickly and increasing the number of shots on goal will translate to the extra points they missed last season.

"I am very pleased with what I've seen in most of the things that we've done," said Arteta. "But we miss something in certain moments.

"That preciseness, that moment that unlocks the result, the moment to turn the result our way."

A key part of how this Arsenal team plays is built around the partnership of right-back Ben White, captain and right-sided number eight Martin Odegaard and right winger Bukayo Saka.

All three had lengthy injuries last season and without them in the side regularly, the Arsenal attack struggled to flow.

In the open training session held at the Kai Tak Stadium, the three were practising interchanging passes and runs, ending the drills with a cross into the penalty area which was aimed at new striker Viktor Gyokeres.

White continuously ran on the outside of Saka to either give him the option to pass for the overlapping full-back to run on to and cross, or dribble into the box himself.

Gyokeres was introduced in the 77th minute as supporters got to see the club's new signing in an Arsenal shirt for the first time.

The 27-year-old is a different profile to the other Arsenal forwards - he is an imposing figure and it is hoped inside the club that his goals will fire Arsenal to a trophy.

Gyokeres plays a lot differently to Kai Havertz, for example - he does not look to get involved with the build-up play as much, instead looking to get into the penalty area or on the end of crosses.

Gyokeres had a couple of half chances, one being a header from a corner which came at him from a difficult angle, but he did not get a chance to show why Arsenal decided to spend up to £64m on him.

"I'm really happy to have them here," Arteta said when asked about Gyokeres and defender Cristhian Mosquera, who also made his first appearance.

"I think they are going to add a lot of value. You see straight away the energy and the quality they are going to bring.

"It was a short time but at least that one is over now and when they play against Villarreal (on 6 August), I'm sure it will be different."

Tottenham were under pressure for large parts of the match but when they did attack, their wingers offered a good attacking outlet.

Wilson Odobert and Kudus were always looking to take on their full-back and Kudus hit the post directly from a corner in the first half.

After the match, Frank was asked about the £55m summer signing from West Ham.

"His hold-up play, the way he takes hold of the ball in tricky situations, his one-vs-one skills and his creating opportunities for the team were top class," Frank said.

"On top of that I think he's working extremely hard. There was a recovery run from a set-piece when he was straining all the way back and he won the ball back.

"That's how he can help the team so much. He will make a lot of the fans excited with his offensive actions and he will also help the team defensively."

The decisive moment of the match was Sarr's strike, which went sailing over the head of goalkeeper Raya.

The Arsenal keeper is tasked with getting involved in the build-up of play by Arteta because of his passing ability.

That means that his starting position is often high and leaves him vulnerable if Arsenal lose the ball in midfield.

Raya conceded a similar goal to Crystal Palace last season, when Jean-Philippe Mateta chipped him when he was off of his line in the Premier League last season.
