Robinho and Sergio Ramos have been linked with moves away from Santiago Bernabeu.
The Real Madrid duo are said to be attracting interest from a host of Europe's top clubs, with Premier League champions Manchester United believed to be among their admirers.
The Red Devils are currently embroiled in an ongoing transfer saga with Los Blancos concerning Cristiano Ronaldo, but may be set to get their own back by making a move for two of Real's top talents.
Brazilian playmaker Robinho has previously admitted that United and Chelsea have enquired as to his availability, while his agent Wagner Ribeiro confirmed that Premier League clubs have approached his client.
"That is certain," Ribeiro told Marca.
"But the decision remains in the hands of Real Madrid because they have a contract with him."
Spanish international defender Ramos is another who is believed to have interested Chelsea in the past, while United are keen to find a long-term replacement for Gary Neville at right-back.
A move to England looks unlikely, though, as the player's agent Rene Ramos revealed that his brother is happy in the Spanish capital.
"There are a number of European clubs interested in my brother," he said.
"But he is happy at Madrid."
