#5 Fabinho
Fabinho has had an unusual rise compared to the other youngsters on this list. His professional career started at Fluminense but he remained an unused substitute in his only squad appearance. In 2012, the Portuguese club Rio Ave purchased the rights to his services on a six-year deal.
One month into life in Portugal, Real Madrid Castilla acquired him on loan for a year. He even appeared for the Real Madrid team as a substitute on one occasion. Monaco then took him to the French Riviera on two consecutive year long loan deals. He became a pivotal component of the side racking up 86 appearances in two seasons.

The French club converted the loan deal into a permanent transfer in 2015 and his performances have only gotten better. His knack of scoring goals has seen him breach the opposition net eight times in the previous season in 47 appearances.
He has been linked to bigger teams across Europe especially to both Manchester clubs and his chance will come soon considering his rapid rise in France. He may not end up reaching the world class right back status, but it wouldn’t be a surprise if he even reaches that position.
