Barca will however be without Dani Alves who is suspended while Masip, Douglas, Bartra and Sandro have not been included in the squad.
Barcelona will break the all time league record for most unbeaten games in a row if they either draw or beat Rayo .
The reigning champions have gone 34 games without a defeat which is a club record and matching the overall Spanish record set by Leo Beenhakker during his time in command of Real Madrid back in the 1988-89 season.
Barca have also won all 12 games in which Turan has featured since making his debut against rivals Espanyol in the Spanish Cup back in January.
The Turkish international winger has started in his sides last two league games and is expected to get the nod again tonight.
The full 18-man Barcelona squad is listed below:
Bravo, Ter Stegen, Vidal, Pique, Mascherano, Vermaelen, Mathieu, Adriano, Alba, Busquets, Rakitic, Sergi Roberto, Iniesta, Arda, Munir, Messi, Suarez, Neymar
