Ronaldo 'will not leave Real Madrid'

London (AFP) - Cristiano Ronaldo will finish his career at Real Madrid, the Portuguese superstar's agent said Tuesday as he put a £300 million ($452 million, 298 million euros) price-tag on the world footballer of the year.

"He is the best player ever in the world. You can't compare him with anybody else," agent Jorge Mendes said of Ronaldo in an interview with the BBC.

"If for any reason the club decide to sell him tomorrow for £300 million, someone will pay," Mendes added.

But the agent said there was no danger of his 29-year-old compatriot, voted the world's best player for a third time last month -- beating Barcelona's Lionel Messi to the award -- leaving Real's Bernabeu Stadium.

"Cristano Ronaldo? One billion. His buyout clause one billion, so it is one billion. It is impossible to find someone like him."

Asked if Ronaldo, who joined Real from Manchester United for a world record £80 million in 2009, would end his career with the Spanish giants, Mendes said "for sure".

"He will not leave Real Madrid," Mendes insisted.
