Fabio Cannavaro believes Real Madrid need Kylian Mbappe so he can follow in Cristiano Ronaldo's footsteps, but feels it will be tough to sign the Paris Saint-Germain star.
Mbappe, 21, continues to be linked with a move to Madrid from PSG, where he has starred during the past three seasons.
Madrid have found it hard to replace Ronaldo, who decided to leave the La Liga giants and join Juventus in 2018.
Cannavaro, who won two La Liga titles with Los Blancos as a player, said Mbappe could be the player the club need to follow what Ronaldo delivered.
