Real Madrid have begun the process of extending the contract of Cristiano Ronaldo.

Florentino Perez initially made the promise of improving Ronaldo's deal after last year's Champions League final in Cardiff.

Ronaldo is believe to view the proposal positively and a new contract is expected to be in place before the World Cup begins.

Ronaldo could go from earning €21 million ($26 million) net per year to €30 million ($37 million) net per year. The improved contract would put him closer to Neymar's €35 million.

Ronaldo's contract won't be extended, however, as it is set to expire in June of 2021.
