Arsenal goalkeepers Peter Cech and David Ospina are unlikely to be fit for Monday's trip to Crystal Palace, Arsene Wenger has confirmed.

Emiliano Martinez filled in between the sticks for the midweek victory over West Ham and is expected to do so again in south London.

"From Wednesday's game nobody should be out," Wenger said. "[Francis] Coquelin is back available after his family problem and will be in contention.

"Overall I don't believe [Petr] Cech will be available nor [David] Ospina."

Martinez, who joined Arsenal in 2012, has only made a handful of first-team appearances for Arsenal.

The 24-year-old will be in line to feature at Selhurst Park and Wenger has full confidence in his third-choice goalkeeper.

"He looked composed and calm [against West Ham]. I know personally he has the quality," added the Frenchman.

Laurent Koscielny will also not feature against Sam Allardyce's side with the Gunners set to make the short trip across the capital aiming to keep their hopes of a top-four finish alive.

Wenger's side could be seven points adrift of the Champions League places when they kick-off in SE25.
