5. Yannick Bolasie
Yannick Bolasie had spent the early years of his career floating around the lower divisions and even took in a spell at Maltese side Floriana. After struggling to establish himself at Bristol City, Bolasie joined Crystal Palace for less than £500k in 2012. Not only was he quickly able to establish himself in the Palace side, he's gone on to become a world renowned star in his own right with his impressive array of skills - his signature 360 flick against Spurs in 2014 even appearing in the FIFA 16 trailer. Born in Lyon, but representing DR Congo at international level, Bolasie is undoubtedly one of the most exciting players to have ever put on a Palace shirt and has been subject to interest from some of the Premier League's biggest clubs.
