Rafael van der Vaart has hinted that he could leave Real Madrid amid reports linking him with a move to Chelsea.
The Holland international has struggled to establish himself at Real since his arrival at the Santiago Bernabeu from Hamburg last summer.
Speculation suggested Van der Vaart could return to Hamburg, but the playmaker has since rejected the rumours.
However, recent reports have linked him with a switch to Chelsea, where Dutch coach Guus Hiddink is currently in temporary charge.
Van der Vaart said in The Sun: "It's flattering when someone like Guus Hiddink is interested as he is one of the best.
"If my World Cup selection is threatened I must think about a transfer."
