Interview with Chief Executive Peter Lawwell.
The highly-rated striker arrived at Celtic Park in 2013 on a four-year contract from Vitoria Guimaraes.
Born in Guinea-Bissau, Balde showed sufficient potential to be recruited into Sporting Lisbon's youth set-up. Released by Sporting at the start of the 2012/13 season, the Portuguese Under-20 internationalist was snapped up by Vitoria and quickly established himself as a key member of the side with his powerful forward play and goals.
He joined Celtic in summer 2013 and made his debut in the UEFA Champions League qualifier against Cliftonville. He has scored three goals for the Hoops - against Partick Thistle, and against Kilmarnock home and away.
