#9 Kylian Mbappe (PSG)
The 19-year-old has already achieved more than what many professional footballers achieve in their entire career. The youngster has already won the Golden Boy award along with 2 Ligue 1 titles, 1 French Cup and 1 French League Cup. He could also become the 2nd most expensive footballer if PSG activate his £180 million clause in his loan deal.
Many have compared the youngster with former Brazil striker Ronaldo. He has got quick feet, a tremendous amount of pace and good finishing skills with 21 goals despite the fact that he was playing wide out on the right wing for the majority of the campaign.
Also, it is no secret that Mbappe is a huge fan of Real Madrid's talisman Cristiano Ronaldo and reports have revealed that last summer he was close to a move to the Bernabéu. According to reports, the Los Blancos are again ready to make a bid to sign the Monaco youngster for £200 next summer.
There is no doubt that Mbappe would improve any team in the world right now, but considering the fact that he is only 19, Madrid could wait for some more time to sign him.
