The eye-watering wages Lionel Messi is being paid by Barcelona have been leaked by El Mundo. (More Football News)
The lucrative contract signed by the Argentina international in November 2017, which is set to expire this year, was said to potentially be worth more than €555million.
According to the Spanish newspaper, that includes annual earnings in excess of €138m - dependent on some variables - as well as a renewal fee of over €115m and a loyalty bonus just shy of €78m.
The report says Messi has earned €29.8m of the €73.5m up for grabs in incentives, making the deal ultimately worth €511.5m to the superstar striker.
That would make the 33-year-old the world's best-paid athlete, seeing him bring in around five times the amount NBA great LeBron James makes.
But against a backdrop of financial woes, with Barca's accounts for 2019-20 showing a gross debt of €820m, have the Catalan giants really got value for their money?
We take a closer look at the figures involved behind the deal and provide a breakdown of Messi's worth to the side.
STRIKING IT RICH
Messi's contract renewal was made official on November 25, 2017, six months after reports emerged of the forward having turned down the club's initial offer.
At that point in his career, he had scored 523 goals in 602 appearances for the Catalans in all competitions - a staggering scoring rate that saw him break a number of records.
The Argentinian has continued to feature regularly for Barca since then, playing 152 times in all competitions.
That totals 12,678 minutes of playing time overall which, using the €511,540,548 figure Messi has received, equates to €40,349 per minute across that period - although this will decrease slightly by June as he continues to play.
The Barca number 10 has scored 126 goals in all competitions - 94 in LaLiga, 21 in the Champions League, 10 in the Copa del Rey and one in the Supercopa de Espana.
Using those same reported figures, Messi has therefore been paid €4,059,846 for every goal he has netted since putting pen to paper on his latest contract.

SCORING FIGURES DECLINING
Barcelona have not exactly enjoyed their greatest period on the field during that time, winning just four trophies - LaLiga twice and the Copa and Supercopa once apiece.
No player in LaLiga has scored (94) or assisted (45) more goals since November 2017 than Messi, while the 277 chances he has created is also a competition-high.
However, the one-club man's goalscoring figures have dropped off over the past two seasons.
Messi scored 36 league goals in 2018-19, two more than the previous campaign, compared to 25 last season and 11 in 17 games so far this term.
In terms of assists, he has just two this campaign, which is a huge decline on the 21 supplied last time out - a LaLiga record, surpassing Xavi's 20 in 2008-09.

Coach Ronald Koeman has not been afraid to leave Messi out of his starting line-up on occasion this season and the statistics appear to show his importance to the team is dwindling.
Going back to 2017-18, the season in which the forward signed his lucrative deal, Barca's win rate in the league dropped from 81.2 per cent with Messi in the XI to 33.3 per cent without.
That is in stark contrast to the current campaign, in which Koeman's men actually have a better win rate without Messi in their starting line-up, albeit over a smaller number of games.
Barca have won 56.2 per cent of the 16 LaLiga games Messi has started this term, compared to 66.7 per cent of the three games in which he has not featured from the outset. They have not lost any of the matches Messi has missed.
