The 20-year-old is among the most sought-after talents in English football, with Premier League clubs jostling for position at the front of the transfer queue.
Palace are said to be looking for around £20million for a player who was drafted into Roy Hodgson's senior England squad on Sunday and it is clear that a sizeable fee will be required to lure him away from Selhurst Park.
Zaha has been reluctant to speculate on what the January transfer window may hold for him up to this point, but he now concedes that he needs to let people know where he stands.
"I have got a lot going on," said Zaha, who is currently spearheading Palace's Championship promotion push.
"I try to take my mind off it. I'm at Palace so I don't need to think about anything else.
"The fans have got loads of love for me, so it's a nice place to be.
"I just have to do what I have to do and forget about everything else. But when January comes I have to decide."
