Las Palmas have completed the signing of former Espanyol winger Wakaso Mubarak on a season-long loan.
The 25-year-old, who is owned by Rubin Kazan, endured an unfrutiful spell with Celtic last season and returns to Spain after a two-year absence.
He is best known for his time at Espanyol during the 2012-13 campaign and is an established Ghana international, with 31 caps and nine goals for the Black Stars.
Los Periquitos aside, Wakaso has also played for Elche and Villarreal in Spain.
