The striker will move to Buriram United later this week, having failed to make a single appearance at Barcelona after his £12 million move to Camp Nou in 2009

Former Barcelona starlet Keirrison has completed a dramatic fall from grace, with the 27-year-old set to join Buriram United from Coritiba this week. 

The striker completed a £12 million transfer to Camp Nou in 2009, having scored 21 league goals for Coritiba the year before prior to a move to Palmeiras. 

Keirrison failed to make a single first-team appearance for Barca, however, and instead embarked on five successive loan spells to Benfica, Fiorentina, Santos, Cruzeiro and former club Coritiba - whom he later joined on a permanent deal - and is now set to complete a move to Buriram.
