On Sunday afternoon Arsenal made it nine wins in a row in all competitions as they showcased, to near perfection, what their manager has been asking for since he took over from Arsene Wenger in the summer.
It turned out to be an easy afternoon's work for the Gunners as doubles from Alexandre Lacazette and Pierre-Emerick Aubameyang either side of a lovely team move, finished off superbly by Aaron Ramsey, ensured another three points away from home for Unai Emery's men.
Here are four things we learned from Saturday afternoon's entertainment.
4. An Old School 4-4-2 Formation Suits Arsenal to a Tee
The absence of Mesut Ozil and Ramsey meant Emery had to alter his formation and he set his team up to play with four at the back, two out wide, two holding midfielders and two out and out strikers. This is the most effective Arsenal have looked under Emery.
Danny Welbeck set about winning everything in the air and chasing every lost cause to ensure Alexandre Lacazette would be afforded chances, and if we have learned one thing about the Frenchman, it's that he does not need more than a couple of chances.
The headache for Arsenal's Spanish boss now, is how does he accommodate the likes of Ozil and Aubameyang into a 4-4-2? Although if this is the only issue Emery has, then it is a very good one to have.
3. Arsenal Are Contenders For a Champions League Spot
The Gunners gave a statement of intent to the Premier League on Sunday afternoon, a 5-1 hammering away from home against any team is impressive. The classic Arsenal problems of the past seem to be vanishing, two world class strikers and a Rottweiler-like holding midfielder have given the Gunners a new dynamic moving forward.
Another Arsenal issue has been there lacklustre performances away from home, however with three away wins already so far this season, there may also be an upturn in something that previously was an achilles heel.
Fans chanting 'we've got our Arsenal back' means the old toxicity at the Emirates may be on the way out, with sights firmly set on breaking back into the big time for the Gunners.
2. Unai Emery Cares Solely About The Team's Performance
The endearing Spaniard Emery has been a brilliant addition to the Premier League thus far in his Arsenal tenure, something that sets him apart from others is his primary focus on performances, rather than results, as he sees them as second fiddle.
For example, on Sunday he wasn't concerned about taking off Lacazette when he is on a hat trick, as his side's performance comes first. He isn't fazed by dropping big name players like Ramsey or Ozil to ensure his team is perfectly set to stop the opposition and play his brand of football.
He has a squad of players now that are well-rotated and believe in his system, resulting in all players in his squad being able to come in and perform under any circumstance.
1. Fulham Look Set For a Serious Relegation Battle
21 goals conceded in eight games is not the sort of statistic for a team that wants to stay up in the Premier League. Fulham are being taught harsh lessons, ones they will have to learn if they are to have any hope in this nonstop league.
The starting point for Slavisa Jokanovic must be his backline, at no point this season so far have Fulham stuck with the same defence and goalkeeper from the previous week, that is a massive problem that becomes more glaring the longer it continues.
The key to survival is a sturdy, solid defence, from which they build forward with the obviously fantastic attacking capabilities of Andre Schurrle, Luciano Vietto and Aleksandar Mitrovic.
