Paul Pogba and M'Baye Niang could leave Juventus and AC Milan respectively in the summer, according to the players' agent.
Mino Raiola claims that the French youngsters will be subject to interest from top European clubs, amid speculation that Real Madrid are keen on Juventus midfielder Pogba.
"Real's interest? It's a much wider discussion," he told Tuttosport. "Exceptional boys like these two are obviously going to be liked by Real. These two are liked by the whole world.
"Right now there are no contracts that can tie down a player to any club. No-one, when you are admired around the globe, can be 100% certain of keeping a player."
Pogba has developed into a key midfielder for Juventus this season, while 18-year-old striker Niang is a budding young talent at AC Milan.
