Thomas Frank believes it, but does anyone else?
The Brentford boss insisted that Arsenal are live contenders for the Premier League title prior to their trip to the Gtech Community Stadium on Sunday, and that was a belief only strengthened by what he saw during their 3-0 win over the Bees.
It was a result which returns the Gunners to the top of the Premier League table for the international break, and had Mikel Arteta purring as he surveyed the lay of the land which has seen his side win six of their opening seven Premier League games to get giddy supporters dreaming that anything is possible.
They're even giving games to 15-year-olds, after all..
So can they go on a run and put together a sustained title challenge from here and actually win the Premier League? We asked our Mirror Football team what they think.
Sam Meade
Short answer - no.
They certainly can, and on this form probably will, finish in the top four. They've been very impressive so far, performing well even in their defeat to Manchester United. However we'll get a far better gauge of where they're at once they've faced Manchester City, Liverpool and Tottenham.
Bottom line is, they're certainly not better than the champions, and will be overhauled by Pep Guardiola's outfit.
What the Gunners have also been is professional, they've played well in games and clearly have a philosophy, but what they've done is win games they should win.
Losing at the likes of Brentford and Crystal Palace is where they've come unstuck previously, but this term they're beating those teams outside the top eight, which is exactly what a side who finished second or third should do. Currently though, they still need to overturn an elite side before they're considered the real deal.
Tom Blow
Yes, although I don't think their start to the season has changed anything.
Arsenal's hopes of winning the title will come down to the fitness and form of their rivals (and themselves, of course).
We saw Manchester United pip Liverpool to second a couple of years ago due to the latter side suffering an injury crisis, and that could happen again. We're also witnessing the Reds endure a poor start this time around.
And Manchester City aren't as good as people think. Erling Haaland is in incredible form, yes, but they've already dropped four points this term. They do stutter from time to time, and the Gunners will certainly give them a good game when their postponed match is rearranged (probably before the World Cup).
Arsenal are a very good side and just need to take it game-by-game. They haven't played badly in any of their seven Premier League fixtures this season and shouldn't be ruled out.
Jacob Leeks
The cliche is that the Premier League is a marathon not a sprint and Arsenal have got themselves off to a surprisingly good start.
Whether they can sustain that is the question, with Erling Haaland and Manchester City looming large. If Mikel Arteta can keep his main starters fit, then the Gunners certainly have a golden chance to beat City to the title.
Liverpool look out of sorts, Chelsea are at the start of a transition and Manchester United still look vulnerable.
Arsenal though are full of confidence, led by the attacking verve of Gabriel Jesus, Bukayo Saka and Gabriel Martinelli.
Arteta's squad is full of quality and contains a strong spine, crucial elements to a title challenge. The Premier League has a history of big shocks and Arsenal winning their first title since 2004 could well be the next.
Mark Jones
There really are two ways of approaching this question.
Will Arsenal win the Premier League? No.
But should their manager, players and more importantly supporters believe that they they can? Absolutely.
Fans need to go on journeys with their clubs, it is where excitement happens and memories are made, and you can also aim for the moon and land among the stars.
A place in the top four would be a superb achievement for Mikel Arteta's side this season, but the relentless slog of Premier League and Europa League matches - remember they've only played one European game as it stands - make sustaining the levels we've seen from Manchester City and Liverpool, the course and distance specialists, in recent seasons look unsustainable for them right now.
If they weren't in the Europa League then there would be a shout for title challenge, but for now such talk can wait.

Can Arsenal win the Premier League? No.
The reason: Manchester City.
Mikel Arteta's men have come on leaps and bounds in the last 12 months and this current side looks as if it could be the best of any we've seen at the Emirates in the past decade.
They play brave, attacking football based around the principles of their manager, while defensively are much more solid than they've been in some time, better at defending set pieces than at any point since the Invincibles and have become much more physically dominant with the arrivals of William Saliba and Gabriel Jesus.
There's no doubt a top four spot is certainly achievable. Perhaps they usurp Spurs and, if they don't overcome their early season issues, Liverpool too.
But we saw against Manchester United that Arsenal are still a work in progress, that they're still not quite as decisive as you need to be when it really gets down to it. The meetings with Liverpool and Spurs at the start of October will tell us more about them.
But backing them to overhaul Manchester City, champions in four of the last five seasons, setting new records for excellence and now with Erling Haaland up top? No, not for me.
Thomas Bristow
They can. Leicester proved even the unlikeliest of teams can. But they won't.
Let's get it right, Arsenal have started the season brilliantly. Barring the blip at Old Trafford, a contest in which Arteta's men really should have wrapped up in the first half, the Gunners have stepped up superbly from last season.
Excellent recruitment, a clear philosophy and a happy dressing room have culminated in an exciting new era at the Emirates. Arteta is even getting the best out of Granit Xhaka!
But to win the Premier League requires a lot of consistency and a lot of luck. Not to mention a big squad. It is the latter point in which Manchester City will overtake the rest during a hectic Christmas and post-World Cup schedule.
Should Arsenal come through that period unscathed they could pull off the previously unthinkable. But, for me, City have enough experience, a big enough squad and a good enough manager to keep their standards up all season long.
Colin Millar
Being top of the table after seven rounds of action with six victories is impressive while the manner of Arsenal’s early-season wins provides plenty of hope for more to come from the Gunners.
Yet sight of this season’s objective should not be lost – Mikel Arteta’s side are aiming for a top four place, which has eluded them since 2016.
Liverpool will come roaring back while Manchester United and Tottenham have also made significant strides since last season. Chelsea cannot be ruled out from that running either.
As impressive as Arsenal have been, the only bona-fide top half side they have faced was a trip to Old Trafford which offered plenty of encouragement but familiar failings.
Anything above fourth is a bonus for Arteta’s team this campaign, with a hectic schedule bloated with European matches and domestic cup obligations likely to stretch them to capacity later in the season.
Felix Keith
In an infinite universe, anything is possible. Arsenal are one of 20 teams who could win the Premier League this season – and they stand a better chance than the vast majority of the rest, given their current position.
The bookies, who are usually a good gauge, make them third favourites, behind the two usual suspects, at around 10/1. That seems a fair reflection.
But you’d have to be brave to put more than a few quid on that. Manchester City have won four of the past five titles and have a squad depth Arsenal cannot match, despite the huge expenditure in the last few summer transfer windows.
An injury to Gabriel Jesus, Bukayo Saka, Gabriel Magalhaes or Aaron Ramsdale would severely weaken Mikel Arteta’s squad.
Eddie Nketiah, Marquinhos, Rob Holding and Matt Turner are not title-winning back-ups. Arsenal have been quick out of the blocks, but I doubt they have the staying power.

No way.
Mikel Arteta has made huge improvements over the summer and there's every chance they could finish in the top four, perhaps even second. But win the league? No chance. Manchester City are just far too good.
Also, I think it would be silly to write off Liverpool so early on in the season. Just look at what Jurgen Kopp and his Reds did last season.
The Gunners have clearly enjoyed a stunning start to the season and they showed just how far they've come in Sunday's win against Brentford.
Given just how terrible they were in west London last season, Arteta needed his side to deliver - and they did.
But I expect the wheels will soon come off their title bid, if you want to call it that.
They don't, in my opinion, have the squad depth that the likes of City have. A couple of injuries and Arteta is left with scrambling around to fill a strong XI and bench. I don't think Arteta expects to challenge for the title either; a top-four finish will suffice.
