With Arsenal's injury crisis seemingly ever-worsening, Arsene Wenger will now have to turn to his third-choice goalkeeper for the Champions League clash against Anderlecht on Wednesday.
Emiliano Martinez, 22, is set to play just his third competitive match for the Gunners with Wojciech Szczesny and David Ospina both unavailable for the tie.
Martinez made his Arsenal debut against Coventry City in the League Cup in September 2012, a 6-1 victory. In his other game he conceded five in the memorable 7-5 victory over Reading a month later.
The 6ft 4in goalkeeper spent part of last season on loan at Sheffield Wednesday in the Championship, where he played 15 matches and kept two clean sheets, and had a previous loan spell at Oxford United.
Signed from Independiente in 2010, Martinez has represented Argentina at both Under-17 and Under-20 level.
Szczesny is suspended for the game after he was sent off at the Emirates in the 4-1 victory over Galatasaray, while Ospina unfortunately picked up an injury during training.
Martinez, who previously went under the name Damian, is a regular for Arsenal's Under-21 squad and is believed to be rated very highly by Arsenal staff.
