Arsenal's hunger and fire as they pursue a first Premier League title in almost two decades burns so brightly that Pep Guardiola was moved to hold it up as an example to his all-conquering Manchester City.
When Guardiola launched an angry broadside in all directions to provoke improvement from the reigning champions after City's 4-2 win over Tottenham, Arsenal was the name that played across his lips with regularity.
It was the most significant indicator of Arsenal's progress and growing maturity under his former right-hand man Mikel Arteta that Guardiola made it clear who he regards as their serious title rivals - even warning they would "destroy" City unless they improved.
