The Eagles beat Watford 1-0 in the promotion playoff at Wembley on Monday afternoon thanks to an extra-time penalty from veteran Kevin Phillips and now Holloway wants to retain the services of both star winger Zaha, who signed with Manchester United in January, and match-winner Phillips, who has been on loan from Blackpool.
"I think he [new United boss David Moyes] would be silly to give me him [Zaha] back," Holloway said.
"Now we're up it might be realistic but who knows?
"He (Moyes) will know the task he's got. Mine will be staying up, his will be winning every week. Good luck to him and good luck to us."
On 39-year old Phillips he added: "I'll keep signing him until he's nearly 50 or 60, if he keeps putting the ball in the net.
"The difficult thing for Kev is living in a hotel once or twice a week because he doesn't need to move his family any more. That's what you lose; you lose that desire.
"I can't wait to see him again and thank him for how well he's played for me."
