Real Madrid are demanding a major hike from adidas in their kit deal.
Marketingdeportivomd.com says Real president Florentino Perez wants to renegotiate terms with the German sportswear giant.
The Madrid giants are being paid less than the €94.5 mllion-a-year Manchester United enjoy with adidas and Perez is now ready to act.
Real want their terms to be raised to €150 million-a-year - and with bonuses to €200 million-a-year.
The demand from Real has already been submitted, with Nike waiting on the sidelines as an interested observer.
