The Argentine ace finally ended speculation over his future in November when he put pen to paper on a bumper deal that ties him to the Nou Camp until 2021.
However, the financial details of that contract have emerged, apparently showing that Messi pockets €100-a-year.
That is almost double what his rival and Ballon d’Or winner Cristiano Ronaldo receives at Champions League holders Real Madrid.
Messi scoops €71million in wages, while the rest of the cash comes from image rights.
He is also in line to pick up another €70m bonus if he stays with the Catalans for the duration of his deal.
It is believed the release clause in Messi’s deal stands at €700m, with only Cristiano Ronaldo and Karim Benzema commanding bigger buy-outs in their contracts.
The 30-year-old has scored 25 goals in 31 games for club and country this season.
His haul has helped Barcelona establish a 16-point lead over Real Madrid in La Liga, while he also fired Argentina to the World Cup.
