5. Barca Paid Over $50 Million For Him
Junji Kurokawa/AP/Press Association ImagesEven though he grew up in poverty, too poor to even buy himself a pair of football boots, Alexis Sanchez would later be worth over $50 million. In 2011, following a three-year stint at Italian side Udinese, Barcelona - one of the biggest and most successful clubs in history -
paid $35 million, along with $15 million in bonus fees for Sanchez's services. The deal meant Sanchez became the first Chilean in history to play for Barcelona, while the forward became the most expensive player in Chilean history. This is all the more remarkable when you consider his humble roots, and that day a town mayor took pity on a young boy and gave him his first pair of football boots so he could realise his dreams. Sanchez's is a story of grit and determination to succeed - two qualities Arsenal fans will appreciate in their newest player.
