Real Valladolid owner Ronaldo says former club Real Madrid should move for PSG star Kylian Mbappe this summer.

Ronaldo prefers the Frenchman for Los Blancos ahead of fellow countryman Neymar due to their age difference.

"Right now, it is not that one is better than another, but if Real Madrid had to make a big investment, they should do so thinking about the future," he said during a webinar hosted by Santander.

"Neymar is 28 years old and Mbappe is 22.

"As an investment, it would be more logical to bring the younger [of the two]," said the Brazilian.
