Real Madrid are interested in Paris Saint-Germain superstar Kylian Mbappe's younger brother Ethan.

Kylian has long been linked with a move to Los Blancos and boss Zinedine Zidane has not been shy in expressing his interest in the Frenchman.

Ethan, 13, is being tipped to follow in the footsteps of his older brother, who at the age of just 21 has already become a phenomenal forward.

Kylian has already won a World Cup and has scored 78 goals in 106 matches for PSG

Ethan impressed at the International Champions Cup Futures tournament last month, playing for PSG's youth side in front of scouts from the Real Madrid set-up, say Diario AS.

Real have long coveted older brother Kylian, and are reportedly lining up a summer move worth a staggering €300million (£254m).

Mbappe has scored 78 goals in 106 games for PSG and was the French league's top scorer last campaign, netting 32 times. He also won the player of the season award.

The striker joined the French giants from Monaco in 2017 for a total fee of roughly £166m - making him the second most expensive player in history. He has also won the World Cup with France.

PSG team-mate Neymar is still the most expensive player in the world at £198m - but if Kylian is lured to Real he would surely smash the current transfer fee record.

Like Kylian, Ethan is a forward, and should he go on to fulfil even some of his older brother's potential then Real would save a fortune by signing him now. His presence at the club would also only serve to make Real a more attractive destination should Kylian be tempted away from Paris.
