#7 Kylian Mbappe
The youngest player on this list, Kylian Mbappe's rise to fame in the footballing world beggars all description. His breakout 2016/17 season at AS Monaco saw the teenage sensation being courted by several European top dogs, with Paris Saint-Germain winning the race eventually.
However, it was the World Cup 2018 at Russia that truly put Mbappe through his paces and quite astoundingly, the Frenchman came through extremely well, winning the Best Young Player and French Player of the Year awards for his performances. His feats at the mega tournament also caused a spectacular rise in his market value.
Before World Cup 2018, the 20-year-old only had one sponsor Nike. In October 2018, he inked a major endorsement deal with luxury watch brand Hublot, therefore replacing Usain Bolt to acquire the title of Hublot's brand ambassador. With $26.6 million from salary and other winnings together with $4 million from endorsements, Mbappe grosses $30.6 million annually.
