Real Madrid president Ramon Calderon remains confident they will be able to register both Klaas Jan Huntelaar and Lassana Diarra for the Champions League.

Marca says while Calderon is still shocked by the gaffe, which could mean coach Juande Ramos having to choose between the two new signings for a Champions League place, the president is confident he can persuade UEFA supremo Michel Platini to allow both to play.

Calderon will lean on support from the Spanish Football Federation to convince Platini to see the matter Real's way.
