Arsenal's squad is well prepared for their match against Brentford and has an extremely strong foundation. Mikel Arteta has stuck by the core of his team throughout and even Gabriel Jesus' injury over the winter didn't derail them.
Now, with three extra first team players added in January and the gradual return of Emile Smith Rowe and Jesus himself, the Gunners are showing signs of true depth. Matt Turner has impressed in his few rotation appearances, Takehiro Tomiyasu was a starting fullback last season and Kieran Tierney is still just 25.
In midfield Jorginho is a different type of player to Thomas Partey but still offers plenty to Arteta and Leandro Trossard has looked lively in his first few games. These players have shown genuine, strong back-up characteristics with many more than capable of deputising when needed.
