Louis van Gaal faces a decision over several senior Manchester United players once his World Cup commitments are over.
United midfielders Anderson and Antonio Valencia are both about to enter the final year of their existing deals, as is attacker Bebe.
All three players would be prime Bosman targets for European rivals and would be free to discuss and sign terms from January 1.
England midfield duo Michael Carrick and Tom Cleverley also have just 12 months to run on their deals.
