#1 Lionel Messi - £162 million

Lionel Messi has shown absolutely no signs of age catching up with him as he has improved his game by leaps and bounds with each passing day.
Notwithstanding his disastrous World Cup campaign, Messi's market value has been mushrooming like no other. The nucleus of Barcelona's roster, the Argentine helped his team run riot domestically in the 2017-18 season as they clinched the La Liga and Copa Del Rey in a grand fashion.
He was a brilliant playmaker-cum-goalscorer for La Blaugrana, scoring 45 goals and assisting a further 18 across all competitions.
While a Ballon d'Or this year seems unlikely for the Argentine, an excellent start in the upcoming season might turn the tables on his rivals and cement his place as the greatest player in the football folklore.
