The north London club snapped up the teenage forward from Fulham last year for a compensation fee.
The 19-year-old has impressed this season and has scored ten times for Arsenal Under-23s in 19 Premier League 2 appearances.
Biereth has also trained with the first team and has made Mikel Arteta’s matchday squad four times this term, which includes once in the Premier League as well.
He insisted that when he was assessing his options last summer a pathway to the first team was a big factor and insists that Arsenal showed him that there was one if he did well.
The forward pointed out that Bukayo Saka and Emile Smith Rowe’s success show that there is always a way into the first team for youngsters at Arsenal.
“When my team and I sat down and assessed my options in the summer, that [route to the first team] was a big factor”, Biereth told The Athletic.
“Arsenal had strikers but they sat me down and showed me if I come in and perform well there’s a clear pathway.
“Maybe not with strikers as much, but with Bukayo Saka and Emile Smith Rowe, if you play well you get in the squad.
“That’s all I’ve got to do.”
Biereth will hope to make his debut for Arsenal as soon as possible before trying to cement a place in the first-team squad.
