Real Madrid star Cristiano Ronaldo is fuming over revelations about Lionel Messi's new deal with Barcelona.

Ronaldo and his agent, Jorge Mendes, has been pushing Real president Florentino Perez over talks about a new contract for much of the year - but have received next to no encouragement.

Ronaldo has argued that last season's Double and Ballon d'Or warrants a pay-hike, though his claims have fallen on deaf ears.

Meanwhile, it's emerged this week that Messi's new four-year deal is worth €50m-a-year - including bonuses - and he has also been handed a €100m signing on fee to be paid in four yearly installments.

Don Balon says the staggering figures has left Ronaldo furious. The Portuguese is on a base €21m salary, despite outstripping Messi both individually and with Real over the past year.
