#8 Sergio Canales – Real Madrid
Sergio Canales was a product of the Racing Santander youth academy and was one of the best upcoming stars when he broke into the first team in 2008. In his first full season with the club, the midfielder managed to score six goals and had four assists to his name while playing a key role in helping his team narrowly avoid relegation.
Jose Mourinho and Real Madrid came calling in 2010 and an offer that would tempt any youngster was tabled for the Spaniard and he signed for the Los Blancos in a £5.1 million deal.
However, the dream move halted a career that could have reached great heights after the player was forced to warm the benches at the Santiago Bernabeu. Canales managed only 518 minutes of playing time in his first and only season with the Spanish giants and was loaned out to Valencia before he completed a permanent move in the following year. Soon injuries started to hit him on a regular basis and it led to his downfall.
