It's the North London derby on Sunday and it promises to be a telling one.
Arsenal are on a staggering unbeaten run of 18 games but that's not to say they don't have their doubters.
They still haven't looked totally convincing against top opposition this season, losing to Manchester City and Chelsea in the opening two games and only managing a draw at home to Liverpool.
Tottenham Hotspur have won their last five games - the last two being very important wins against Chelsea and Internazionale.
It's been a brilliant run of games and victory on Sunday would see a season that had initially looked difficult firmly become a promising one.
Something has to give - either Arsenal's unbeaten run ends or Spurs see their winning streak stop at five - making an already tense occasion become just a little bit more special.
And to highlight that, Gunners forward Pierre-Emerick Aubameyang has revealed that he may have something special of his own planned for the match.
In an interview with Sky Sports, Aubameyang talked about the potential return of his superhero mask celebration - a trademark that we haven't seen in quite some time.
The Gabon international was known for wearing a Spiderman mask when he was at Saint-Ettiene, whilst he once broke out a Batman mask for Borussia Dortmund's derby with Schalke 04.
"We will see [if I bring out a mask]," he told Sky Sports. "It depends on my mood. I remember the derby when I put on the mask of Batman with Dortmund, I had the idea on the morning of the game.
"I called my cousin and said okay, go to buy this mask and it depends on the mood - I will see if I feel good maybe, why not. I'm in a good place now so we'll see."
Speaking of the birth of the celebration, Aubameyang explained that it began with honouring a friend on his birthday.
"The first time I did it was with Saint-Etienne in France," he said. "And that was because it was one of my friend's birthdays who had played with me before.
"He came on the pitch with the full Spiderman kit when I was younger, and I said I would do it one day. It was his birthday so I did it."
Will we see it again this Sunday? Well, he'll have to score first - and his last meeting with Spurs saw him fail to register a single shot.
And if he found it difficult last time, Spurs may have just found a little extra motivation to stop him from scoring.News Now - Sport News
