#2 Keirrison
Keirrison de Souza Carneiro actually made it to Barcelona, but didn’t play a single game for the Catalan side. Instead, he was sent out on loan by then manager Pep Guardiola.
The striker signed for Barcelona in July of 2009 for a fee of €14 million, plus €2 million in add-ons, a huge sum for someone who left without playing a minute of football for the club.
Despite him being highly rated, Guardiola clearly didn’t feel that he was Barcelona material. After being loaned out to Benfica a mere six days after joining the Spanish giants, he would also be loaned to Fiorentina and then Santos.
Keirrison would make a permanent move back to Brazil after agreeing a free transfer with Cortiba in 2014. He reportedly flew to Thailand, last month, to sign for Buriram United, but the transfer was cancelled due to both sides hitting an impasse.
