The 27-year-old, who joined from Malaga in the January transfer window, has made 14 appearances this season for Arsenal and also featured in Spain's penultimate World Cup qualifier against Belarus.
He is also in the squad for his country's upcoming friendlies with Equitorial Guinea and South Africa, with the former set to take place on Saturday.
He believes that his move to Arsenal has helped keep him in coach Vicente Del Bosque's plans and he will now look to do everything he can to remain there.
When asked if moving to England had boosted his international chances, Monreal told Marca: "I think so yes.
"I was at Malaga for 18 months and I grew a lot as a player. The move to the Premier League is a jump in quality and a jump forward. I think being part of a team like Arsenal helps.
"I'd like that (to play in the World Cup). I'm aware that it's not going to be easy, also partly because I'm not getting as many minutes as I would like with Arsenal.
"I'm going to continue fighting and working hard because I really want to be at the World Cup."
