5) Keirrison
The 6ft-tall Coritiba striker took Brazilian football by storm in 2007, as he drove his team to the 2nd tier title with 21 goals in the season. The following year, his 41 goals led them to the league title and alongisde it, a plethora of individual awards including – Best Player, Best Striker, Golden Shoe & Best Newcomer.
The following season he joined Palmeiras, scoring 24 goals and earning a move to FC Barcelona. Up until then he had averaged a goal every other game – but that was the end of that.
From 2009 to 2012, he would go on a tour of four clubs in three nations, scoring only seven goals. Then, he went back where it all started, his alma mater of Coritiba. The exciting young striker they had sold just a few years before could only net five more goals in the following two years. That’s an astounding return from the man who had won them the league title so convincingly just years before.
The reunion ended sourly, with Keirrison suing the club over unpaid debts, and refusing to play because he “would not be ready". In their director’s words, what he really might’ve meant was that, “he checked his bank account and the money was not there yet".
He was last seen in Thailand, as negotiations with Buriram United broke down in January 2016.
