One thing Mikel Arteta has consistently stressed during his time as Arsenal manager is the non-negotiables.
The Spaniard has shown his ruthless streak when needed, offloading the likes of Matteo Guendouzi and former captain Pierre-Emerick Aubameyang following disputes regarding the player's attitudes. "There are some non-negotiables", Arteta said when he became Gunners boss in December 2019.
"The demands we put on the team, the commitment, the energy we put in, that dominance. We are the biggest football club in England, and we have to play a little bit with that arrogance, that belief."
