The first round of this season's Premier League has flown by and has produced many intriguing storylines.
Arsenal retained top spot with a 4-3 win over Luton, while Liverpool stayed on their heels by beating Sheffield United 2-0 in Chris Wilder's first match at Bramall Lane.
But defending champions Manchester City lost 1-0 to Aston Villa to extend their winless run to four games, while there were also defeats for top four hopefuls Tottenham and Newcastle.
Meanwhile, Erik ten Hag's Manchester United bounced back from last weekend's defeat at St James' Park to seal a 2-1 home win against Chelsea.
After 30 goals were scored in the 10 top games, Mail Sport picks 10 things we've learned in recent days.
Mikel Arteta's Arsenal remain top of the table after their latest win over Luton

Arsenal leave it too late again
Things almost went completely wrong for Arsenal on Tuesday evening. Playing in a hostile atmosphere at Kenilworth Road, the Gunners twice threw away leads before falling behind after two errors from goalkeeper David Raya.
In the past they may have given in and accepted that it wasn't their night. But not this Arsenal side. Kai Havertz leveled them on the hour mark, and then they continued to push for a winner well into stoppage time.
They finally got their reward in the 97th minute when Declan Rice headed home Martin Odegaard's cross to seal all three points.
Mikel Arteta's men have made late winners their trademark this season and confidence is growing that this could finally be the season when Arsenal end their title drought.
The jubilant scenes at the final whistle certainly suggested the north London outfit felt they were onto something special.

Man City are vulnerable
Gary Neville accused City of being complacent after the weekend's draw against Tottenham, but Pep Guardiola's side still had more than enough chances to win the match in that game.
The same couldn't be said after their loss at Villa Park. City had just two shots in the entire match – both in the same passage of play – while Villa had 22 attempts on target.
In reality, the 1-0 scoreline flattered City. They were thoroughly outplayed from start to finish and the balance of the team seemed all wrong.
The team looked lost without the suspended Rodri, and Kevin De Bruyne's return from injury cannot come soon enough for the champions.
At the moment, City look vulnerable and they need to sort things out quickly if they want to become the first Premier League team to win four titles on the trot.
Aston Villa is the real deal
Let's not take anything away from Villa. They were exceptional on Wednesday nights and have been for most of the season.
This week was always looking like a decisive week for Unai Emery's side, with the Villans hosting City and Arsenal in the space of three days.
They came through the first of these two challenging matches impressively well, and should have ended the match well before Leon Bailey's deflected 74th-minute winner.
Villa smothered City, pushing them all over the pitch and forcing uncharacteristic errors. It doesn't seem fair to single out individuals; this is a well-trained team that knows exactly what is expected of them.
They are now just four points off first place and have the chance to move to within one point of Arsenal if they can beat them on Saturday night. A title challenge may be a step too far at this stage, but Villa are certainly in contention for a top-four finish.

Ten Hag receives a response
United were awful at Newcastle on Saturday, with Marcus Rashford and Anthony Martial receiving particularly heavy criticism.
The mood around Old Trafford hardly improved over the week, with some reporters excluded from Erik ten Hag's press conference for not contacting the club for comment before the stories were published.
Ten Hag desperately needed a response from his players against Chelsea and he got it.
After dropping Rashford and Martial, Ten Hag watched as Scott McTominay's brace either side of a Cole Palmer goal gave United a narrow victory.
It wasn't a perfect performance and United still looked far too open at times, but it was an important result and an improved display. The Red Devils must now back this up when they host Bournemouth on Saturday, otherwise the pressure on Ten Hag will increase again.
Chelsea still has a long way to go under Pochettino
While United can take heart from their performance at Old Trafford, Chelsea were very poor.
Pochettino branded Chelsea's performance in the 4-1 defeat to Newcastle last month as the worst he had experienced since arriving in the summer, and this was not much better.
The Argentine pointed out that fatigue was a factor, and it was a quick turnaround for the team after their weekend win over Brighton, which saw them play more than half the match with ten men after Conor Gallagher's red card.
But it still wasn't good enough and Chelsea still looks soft at times, especially away from home.
They travel to in-form Everton on Sunday and if they don't step up their game, they will also leave Goodison Park empty-handed.
Everton is ready for battle
The wind was taken out of Everton's sails in their first match after their ten-point deduction by an Alejandro Garnacho wonder goal.
But they bounced back against Nottingham Forest this weekend and earned their win against Newcastle on Thursday.
Granted, they had a boost from Kieran Trippier, who had a night to forget, but the Toffees created plenty of chances and to the cheers of the home crowd, they eventually got their reward.
Emotions were running high at the final whistle, with Jordan Pickford taking on Bruno Guimaraes before others quickly got involved, but most importantly the win took Everton out of the bottom three.
Pickford and Everton showed no signs of backing down during or after the match, and this attitude has given them every chance of staying in the competition despite their ten-point penalty.
Newcastle look devastated
Newcastle fell apart in the final 15 minutes at Goodison Park, which is no surprise given the injury problems and schedule at the moment.
They produced three big performances in a week against Chelsea, PSG and Manchester United, but this was a step too far.
With the same XI for the fourth game on the trot – minus the injured Nick Pope – Newcastle ran out of steam in the closing stages and Everton took full advantage.
The Magpies have been very unhappy with the number of long-term injuries they have suffered this season, with Eddie Howe reluctant to move to his bench in the last four games, instead relying on the starting eleven to get the job done.
That may have to change soon, because the team looked devastated on Thursday. Fresh legs are needed, and Howe may need to consider throwing some squad players and academy talent into the mix in some matches to prevent his best players from going into the ground.
Postecoglou's one-dimensional style proves costly
The mood changed at Tottenham on Thursday.
The team had gone four games without a win before West Ham visited the Tottenham Hotspur Stadium, but there was still widespread optimism that Ange Postecoglou's ultra-attacking style of play would pay off. However, it fell flat against the Hammers.
For the fifth game in a row, Tottenham started well and took the lead. For the fifth game in a row they failed to win.
The longer the match went on, the more West Ham got into it, and in the second half Spurs seemed to run out of ideas. David Moyes' men then took advantage of Tottenham's defensive mistakes to turn the game around.
Postecoglou is dealing with an injury crisis at the club, but his tactics have still been questionable. There were times when his team seemed to pass the ball for ball's sake, and the lack of width was alarming at times.
Spurs have been very entertaining this season and have deserved the plaudits they have received, but Postecoglou may need to adjust things as the teams look to sort Tottenham out.

Liverpool are having a great time, but Klopp is not
Liverpool were not at their best against Sheffield United, but still came away with a comfortable 2-0 win.
The highlight of the match was undoubtedly Trent Alexander-Arnold accidentally flashing his backside just before taking the corner that set up the opening goal for Virgil van Dijk.
Fans certainly saw the funny side, but Jurgen Klopp didn't seem to be in the best mood after the match.
The Reds boss snapped back at Amazon Prime presenter Marcus Buckland after he tried to play down the fact that Liverpool would have another match at 12.30pm on Saturday, this time against Crystal Palace.
The news that Joel Matip will probably miss the rest of the season with a serious knee injury will not have cheered him up either.
Kuiper on the edge
Steve Cooper may have expected to be sacked after his Nottingham Forest side suffered a humiliating 5-0 defeat at Fulham on Wednesday.
It was Forest's fourth defeat in a row and by far the worst of all.
However, he has been given one more game to save his job, with Forest traveling to Wolves on Saturday.
Cooper apologized to the traveling fans at Craven Cottage, and he still appears to have the support of the majority of them.
But defeat at Molineux would certainly spell the end for him at Forest, with owner Evangelos Marinakis looking set to move in a different direction.
