Martinez, who moved to the Gunners from Independiente in 2010, kept three clean sheets in five appearances for the club last season.

And the 24-year-old will now look to impress for Getafe, who are back in LaLiga after securing an immediate return from the Segunda Division. 

Getafe beat Tenerife in the promotion play-offs final to reach the top flight and will start its league campaign at Athletic Bilbao on 21 August.
