#1 Kylian Mbappe- €218.5 million

With a market value of €200 million, PSG's Kylian Mbappe is currently the most valuable footballer in the world at the moment.
The French international made his debut in 2015 at the tender age of 16, however, he got his breakthrough in the 2016-2017 season. He was one of Monaco's best players during that season as they clinched the Ligue 1 title right under the noses of PSG.
AS Monaco also reached the semi-finals of the Champions League in the 2016-2017 season and Mbappe played a vital role for the team, scoring 6 goals in their European campaign.
His impressive performances at AS Monaco impressed PSG and they initially signed him on-loan (with a deal in place to sign him permanently in 2018) in the summer of 2017. He was a part of the FIFPro World XI: 2018. He scored 13 goals and assisted further eight in the league during the 2017-2018 season.
He is in a brilliant form this season as well and has registered 18 goals and 6 assists in 15 Ligue 1 games thus far.
