#9. Dani Alves: £28.5 million
The Brazilian full back is a huge presence for Barcelona and the Selecao and was enjoying a great season with Seville back in 2007 before the Catalonian giants were alerted of his presence. Indeed the Spanish giants did not think twice before forking out 28.5 million pounds to the Andalusia-based outfit. The amount was really steep but in all honesty, Barca were rewarded with their faith in the scouting network. As time would tell, Alves would go on to become an ever present for his team in the defense while also showing his attacking credentials that helped the team to multiple domestic, continental and global honors.
