Two of the Premier League's form teams go head-to-head at the Amex Stadium when Arsenal travel to face Brighton.
You might think that it is Brighton who are the 'surprise' part of that equation, but actually it's Arsenal.
The Gunners looked like a veritable crisis club just a few weeks ago, but they have since strung four wins together, culminating in a morale-boosting 3-1 battering of bitter rivals Tottenham last week.
Brighton, meanwhile, have started the season so well that they would have gone top had they beat Crystal Palace last time out.
Sadly for Seagulls fans, they were not able to do that, although they will have been happy to escape with a momentum-maintaining draw thanks to Neal Maupay's injury-time equaliser.

Brighton vs Arsenal best bets
Both teams are in good form and you wonder whether they would settle for a draw right now in order to preserve their unbeaten runs.
Goals do look likely before we get to the inevitable stalemate, so back both teams to score.
Last three meetings
Arsenal 2-0 Brighton (Premier League - May 23, 2021)
It was the Nicolas Pepe show when these two sides met last time, with the damage being done at the start of the second half.
The Ivorian has often disappointed since signing for the Gunners, but he was close to his best against the flapping Seagulls.
Brighton's impressive resistance was broken four minutes into the second half, with Pepe then wrapping up the points on the hour-mark.
Brighton 0-1 Arsenal (Premier League - December 29, 2020)
It was Arsenal who took all three points in this fixture last season too, although they were made to work very hard for it.
Again the first half was tightly contested and again Arsenal wrapped up the points after the break.
This time it was Alexandre Lacazette who was the matchwinner, with the substitute pouncing shortly after coming on.
Brighton 2-1 Arsenal (Premier League - June 20, 2020)
Brighton scored a memorable win in this one, and it highlighted just how fragile Arsenal can be under Mikel Arteta.
That man Pepe gave Arsenal the lead in the 68th-minute, but Brighton hauled themselves back level just seven minutes later courtesy of Lewis Dunk.
Just as the game looked to be heading for a draw, Neal Maupay netted a winner deep into injury time.

Seagulls swooping for regular points
It would be wrong to describe Brighton as perennial strugglers since they reached the Premier League. However, it's also fair to say they have not really picked up points with a great deal of regularity - until now.
The Seagulls have made a blistering start to the season, winning four of their six matches and drawing another.
However, it's also fair to say that Brighton haven't had the most testing start to the season. The Toffees are the only team they have played with lofty aspirations, so it's still a bit of an unknown as to how sustainable this run is.
Are Brighton genuinely transformed into a top-half force this season? Or are they just making hay while the sun is shining? Only time will tell.
Gunners starting to fire
A the end of August, it was becoming hard to envisage Mikel Arteta lasting much longer after watching his Arsenal side trounced 5-0 at Manchester City.
The vultures were certainly circling and there didn't really look like an obvious way out for him.
He, though, has plotted a very un-Arsenal routed out of the mess they were in: he made things scrappy. However, in typical Arsenal fashion, he also focused on clean sheets.
It worked, too, Back-to-back 1-0 wins against Norwich and Burnley got them back on track, and they maintained that momentum with a confidence-boosting win over Wimbledon in the EFL Cup.
Last week was when it all came together, though, with a 3-1 home win against Tottenham in the north London derby.
Just how much that was down to Arsenal doing well and Spurs being atrocious is up for debate, but either way the Gunners look like a completely new side from the one that started the season.
Nicolas Pepe has three goals in Arsenal's last three matches against Brighton, so he is a man who clearly enjoys playing against them.
Pepe was dropped to the bench for Arsenal's win over Tottenham. However, his record alone in this fixture will surely demand involvement at some point so he becomes a good anytime goalscorer bet.
Neal Maupay is definitely Brighton's main man in terms of goals, but it might just be Danny Welbeck who will be the story here.
Former players seem to haunt their old clubs with weird regularity, so Welbeck opening the scoring would surprise no one.
