Emiliano Martinez says he will use his loan spell with Getafe as another learning experience as he ultimately eyes a place at Arsenal in the future.
The 24-year-old Argentinian shot-stopper, who joined the Gunners from Independiente in 2010, has agreed to join the recently-promoted La Liga side for the 2017/18 season.
He has previously been loaned out to Oxford United, Sheffield Wednesday, Rotherham United and Wolverhampton Wanderers, having made five first-team appearances for Arsenal last season.
In an interview, Martinez said: "I came from nothing and I'm at Arsenal now, one of the biggest clubs in the world, but I'm never satisfied.
"I was third choice fighting for second spot, so maybe the season after I will fight for number one.
"You always need to give more at Arsenal. It's never enough and that's what I try to do."
He added: "I’ve always wanted to improve. It’s never enough for me. My kicking is good but I want to have the perfection of a goalkeeper, even on crosses. I know I’m good on crosses but I still do 50 crosses in training.
"I look what I can do and what I can improve with the other goalkeepers. I’m always trying to improve myself. If you want to play for Arsenal or be at the top level for many years, that’s what you need to do.
