Real Madrid are set to complete a new record-breaking deal with sports manufacturer Adidas worth around €140m (£107m, $152.8m) a season, according to Marca. The Spanish publication claims that the La Liga giants will sign a 10-year agreement before the end of the season to overtake Manchester United current world record sponsorship of £75m a season in another chapter of the two European giants economic battle.

The Football Money League report by consulting firm Deloitte recently revealed that despite Real Madrid's trophyless last season, they remain the richest football club in the world for the eleventh consecutive year with total earnings of €577m in the 2014-15 campaign, ahead of the €560m for treble winners Barcelona and the €519.5m of Manchester United, who slipped one place to third.

Marca suggest that Los Blancos are ready to widen the gap further in the coming years by signing a new record deal with Adidas to regain the position they lost in the summer of 2014 after Manchester United secured a contract to become the club with the most expensive kit. The Premier League giants then signed a £75m a season deal with Adidas for ten years after they decided to end their previous sponsorship with Nike, who paid then just £23.5m a year.

Real Madrid had until then the previous biggest deal with a 2012 deal worth £31m year deal also with Adidas until 2020.

Marca reports that now Los Blancos are ready to renew that deal to regain top spot with a new £107m a season deal, three times the value of the current agreement and £32m ahead of the Manchester United's.

The Spanish publication points out that Bayern Munich last summer signed a 15-year deal with Adidas, longer but less valuable than that expected to be signed by Real Madrid.
