Kylian Mbappe has been hailed as "an exceptional player who makes the biggest clubs dream" as Paris Saint-Germain attempt to fend off interest in the France star.
The 21-year-old became the first teenager since Pele to score in a World Cup final two years ago, and he has kicked on since helping Les Bleus to that global triumph.
Former France and Manchester United striker Louis Saha says Mbappe is "the most valuable player on Earth", and claims it is only natural clubs such as Real Madrid should be sniffing around.
