Unai Emery will lead Arsenal into his first north London derby on Sunday afternoon.
The Spaniard has been a breath of fresh air at the Emirates after a few years of stagnation under Arsene Wenger.
Arsenal are on an 18-game unbeaten streak and look poised to actually challenge for the top-four in 2018/19 - something they didn't really do last season.
However, Tottenham come into the fixture in a fine vain of form. Mauricio Pochettino's side were jaw-droopingly good in their 3-1 win against Chelsea.
And they also kept their Champions League hopes alive with a well-deserved 1-0 win over Inter Milan on Wednesday.
It's going to be tough for Emery's side, with the boss set to make a number of huge calls when it comes to his starting XI.
One of those decisions will be on Aaron Ramsey, who's had to settle for a bit-part role this season following failed contract negotiations.
The Welshman started and scored in the 3-0 win against Vorskla on Thursday and Arsenal legend Ray Parlour believes he must be on the team sheet tomorrow.
He also believes he's the man who could act as the 'leader' for Emery's side.
“My only worry for Arsenal is there aren’t many that have played in too many of these derbies," Parlour said, per The Sun.
“The name that stands out I guess for Arsenal is Aaron Ramsey. I know he’s been out in the cold but perhaps it’s time for Unai to utilise him.
“Ramsey should be in the dressing room, alongside Steve Bould, giving that rousing speech telling everyone what the fans want and expect from this game."
“My first one was around 1991 and there were some big names in that dressing room like Bouldy and Tony Adams who would let you know what they expected in a game like this.
“Like Ramsey though, I didn’t really need the history lessons as I had been familiar with this rivalry since I was 14 as a youth player.
“But the foreign boys coming in will need one, and that’s where Ramsey can influence proceedings.”
