Celtic have announced a season-long loan deal for winger Mubarak Wakaso.

The Ghana international joins from Russian side Rubin Kazan.

Part of Ghana's 2014 World Cup squad, the 24-year-old joined Rubin Kazan last summer after a five-year spell in La Liga with clubs like Villarreal and Espanyol.

Celtic suffered the disappointment of missing out on the Champions League group stages last night after a 1 - 0 home defeat to Slovenian side Maribor.
