Premier League weekend: Five things we learned.

Here are five things we learnt from this weekend's Premier League games, including a lesson on set pieces from Arsenal's win over Tottenham, Everton's implosion, Arne Slot's first defeat as Liverpool manager, and Newcastle United's unbeaten start.

Set pieces are one of Arsenal's best weapons—and Spurs' Achilles' heel.

It's the usual script for Tottenham: dominate the ball, generate more chances than the opposition, and surrender from set pieces. Mikel Arteta understood this better than anyone else.

Arsenal remained defensively disciplined throughout the encounter, even as Spurs knocked on the door repeatedly, hoping for an opening.

However, it was the Gunners who struck first, from a corner. They crowded the six-yard box to keep Guglielmo Vicario out, while Gabriel breezed past Cristian Romero to score. The Argentine center-back let his man go way too easily.

Ange Postecoglou has been resolute in his refusal to place a premium on set pieces, but they've proven too expensive for his team and too profitable for their north London rivals to ignore any longer.

Arsenal has scored 23 goals from set pieces (excluding penalties) since the start of last season, more than any other Premier League team during that time.

Meanwhile, only Nottingham Forest (23) has conceded more set piece goals than Spurs (18) across both the 2023-24 and 2024-25 seasons.

Something needs to change.

Everton has (obviously) hit its pinnacle. Everton

Speaking of history repeating itself, Everton once again squandered a two-goal lead before losing 3-2. Two-nil is the most dangerous scoreline for the Toffees.

Aston Villa deserves all credit for fighting their way back into the contest, particularly Ollie Watkins, our Player of the Week. However, Sean Dyche's side suffered an incredible collapse.

The fans have been through a lot over the years, but they must be astounded by what they see from the squad right now. They are unable to prevent themselves from tripping on rakes at every turn.

Everton remain at the bottom of the Premier League table, with no points from their first four games. The belief that they can put up another struggle for survival must be diminishing quickly.

Arne Slot's Liverpool are not unbeatable after all.

It was unavoidable at some time, but few anticipated Liverpool's ideal start under Arne Slot to be derailed by Nottingham Forest on their home turf.

The Tricky Trees uncovered some flaws in the Merseysiders' armour that had not been exploited in the first three games, which they won without allowing a single goal.

Following the game, Slot gave an honest evaluation of his team's performance, saying that they fell short of the Premier League standard. They won't have long to nurse their wounds, though, as they head to the San Siro on Tuesday for a Champions League match against AC Milan.

Jadon Sancho still has it.

Chelsea raised eyebrows when they signed Jadon Sancho on loan with a buyout clause in the summer. The Blues already had a plethora of wide attackers, but they were signing one who had rarely featured for Manchester United in the previous year following a dismal few years at Old Trafford.

If Saturday night's performance is any indication, it could prove to be a masterstroke. The winger came in at halftime during their visit to Bournemouth, with the home side leading, but his wing play reversed the game's course.

The ball stuck to Sancho as he entered the pitch, and the Cherries were unable to dispossess the 24-year-old. He created two chances, one of which culminated in Christopher Nkunku's victory.

A great method to introduce yourself as a Chelsea player.

Newcastle are channelling the Entertainers with an unblemished start.

Despite a string of disappointing performances, Newcastle United is now unblemished and third in the Premier League table after a comeback victory over Wolves. They're not playing in the style of the great Entertainers of the 1990s, but there are some similarities between the two.

With 10 points after four games, the Magpies have had their greatest start to a Premier League season since the 1995-96 season, when they won their first four games under Kevin Keegan.

This year's away kit is inspired by that memorable season.

"It is a great start to the season in terms of results," Fabian Schar added later. "Ten points in four games is impressive. In terms of performance, we can make significant improvements. "Great start, but we need to improve our performances."
