It's a good time to be an Arsenal fan. 

The Gunners began their 2020/21 Premier League campaign in style, beating newly-promoted Fulham 3-0 to go top the table on match week one. 

On top of that, the news that supporters have been desperately waiting for was finally confirmed on Tuesday afternoon.

Pierre-Emerick Aubameyang has signed a new three-year contract and will stay at the club until 2023. 

Life in north London is pretty sweet right now - and much of that is down to Mikel Arteta. 

The young manager has completely transformed Arsenal since taking over from Unai Emery last December. 

He's achieved so much in such a short space of time and his first full season has only just kicked off. 

Arteta has already achieved a lot at Arsenal

Let's check out exactly how Arteta has transformed Arsenal into genuine contenders once again. 

A winning mentality

In recent years, the Gunners have had a terrible record against the Premier League's traditional 'top six' but that's changing under Arteta. 

Last season, Arsenal beat Manchester City, Chelsea, Manchester United and Liverpool. 

Think that's a fluke? Well, think again, because Arteta has already bested Jurgen Klopp's Reds twice, picking up from where they left off in this season's Community Shield.   

Arsenal are winning again

Delivering silverware

Talking of the Community Shield, it shouldn't be forgotten that Arteta has already delivered two trophies... in just eight short months. 

Winning the FA Cup against Chelsea was a huge deal. Very few backed Arsenal to beat the Blues and there's also the added bonus of ensuring qualification to the Europa League too. 

Perhaps you should put some money on the Gunners lifting a European Cup come May?

Playing with a new philosophy

Not only is Arteta delivering silverware, but he's doing it the right way too, with a new philosophy. 

Arsenal are playing some beautiful, free-flowing football at the moment, which is a far cry from what supporters saw under Emery. 

Saturday's performance against Fulham was the perfect example of that. The Gunners were absolutely brilliant. Oh, and they're capable of winning scrappy games too, that's a huge bonus. 

Arsenal can play good football

Making big signings

To challenge for a top-four spot this season, Arsenal needed new signings... and they got them.

Two new boys made their debuts against Fulham - Willian and Gabriel. Both were fantastic too. Gabriel scored one of the goals and won the Man of the Match award, while Willian set all three up. 

Don't bet against the Gunners making more signings before the window closes either.

Convincing Aubameyang to stay 

Perhaps Arteta's biggest achievement so far is convincing Aubameyang to stay. The striker's future has been up in the air and it was thought even an FA Cup win might not have convinced him to re-sign.

But he has. Arsenal's star man has signed a new three-year deal and he's clearly buying into Arteta's vision, otherwise, he would have gone elsewhere. 

Just remember, Aubameyang could have left to play Champions League football, but instead, he'll lead the club as captain and try to ensure they get back into Europe's elite competition. 

Aubameyang stays at Arsenal

Arteta really has done a brilliant job - and it's that last point we want to finish on. 

The next goal has to be getting back into the Champions League. If Arsenal can qualify for competition this season, then Arteta will surely stake a claim for the Manager of the Season award.
