The agreement with Bukayo Saka is more important than the £250m outlay Arsenal made to bring in eight new players in the summer.
Saka's importance on the pitch, alongside his bond with supporters and his journey from the academy, make his position almost impossible to replicate.
His new deal commits the 24-year-old to the club into the peak years of his career and - after several seasons with numbers that match elite wingers across the game - Arsenal will benefit from the progression he could still achieve.
The second half of this season is crucial for Saka as he looks to help Arsenal lift a major trophy for the first time since the FA Cup in 2020.
Mikel Arteta can rely on him and he is one of the reasons why the majority of Arsenal's attacking play goes down the right - the side Saka plays on.
The forward is also set for an important summer with England at the World Cup.
Three Lions fans will hope that after a season of success with Arsenal, he can also deliver for his country on the biggest stage.
