West Ham are chasing Paris Saint-Germain left-back Fode Ballo-Toure.
The highly-rated 20-year-old looks certain to leave the French capital this summer with his contract set to expire.
Madeinfoot says the Hammers have been scouting Fode after learning of his impressive performances in PSG's youth side and this season's UEFA Youth League.
But with the youngster available for nothing, West Ham aren't the only side gunning for his signature.
Liverpool, Everton and Tottenham are all closely monitoring his situation.
