The 28-year-old goalkeeper joined the Gunners from New England Revolution last summer.
He has played as second fiddle to Aaron Ramsdale but has always turned up when he was needed.
He has made a total of seven appearances this season and is yet to feature in the Premier League.
Turner told CBS Sports Golazo: ‘I’m not the type of person who takes their job lightly.
‘I want to be playing every single chance I can get. I show up to training with the right mentality. I work really, really hard to improve in the areas I need to.
‘I’m trying to compete to get onto the field. I think Aaron Ramsdale and I have become better goalkeepers from challenging each other.
‘I hold him accountable and he holds me accountable. We’ve been developing a close relationship which has pushed us both forward.’
Nonetheless, Arsenal have a top-quality shot-stopper as back-up to Aaron Ramsdale in case of any mishap.
