The French sensation has been heavily linked with a number of clubs, and his compatriot claims the Spanish side should sign him this summer
Real Madrid should sign Kylian Mbappe and then loan him back to Monaco for the benefit of his development, according to Franck Leboeuf, who thinks the forward could become "the new Ronaldo".
Ex-France defender Leboeuf believes Les Bleus' new star would be best served by spending another season with Monaco, but understands the Ligue 1 champions would struggle to resist a world-record offer for the 18-year-old.
Lebouef therefore believes a sign and loan strategy from Madrid could be the best solution after Mbappe discussed the European champions' interest in him this week.
