Pio Pio did not have any fitness problems heading into their game with Mallorca last weekend, and no injuries have been reported since, so Martinez is expected to have a full complement for the clash with Barcelona.
Martinez has guided the team to four wins from his six matches since taking charge last month, and a 4-2-3-1 formation should again include on-loan Wolverhampton Wanderers forward Fabio Silva in the final third.
Silva has scored four times in 10 La Liga appearances this season, including three in his last five appearances.
Sandro Ramirez represented Barcelona between 2009 and 2016, making 32 appearances for their first team, and there is again expected to be a spot for him in the final third of the field on Saturday afternoon.
There is a question mark when it comes to the spot down the left, with Alberto Moleiro pushing to be included, but it is likely that Manu Fuster will keep hold of his starting role for this contest.
Kirian Rodriguez is a certain starter for Las Palmas, most likely in the number 10 position, while Jose Campana and Dario Essugo should continue as the midfield two for Pio Pio at Estadi Olimpic Lluis Companys.
Las Palmas possible starting lineup: Cillessen; Rozada, Suarez, McKenna, Munoz; Essugo, Campana; Sandro, K Rodriguez, Fuster; F Silva
