The outspoken Crystal Palace boss encouraged the on loan Manchester United winger to impress on a consistent level in order to catch the eye of Louis van Gaal and Roy Hodgson.
As one of Sir Alex Ferguson's last ever signings for Manchester United, and a big money one at that, it is hard to believe that Wilfried Zaha should be destined for anything other than a career at the very top.
Zaha made his second debut for Palace in Warnock's first game in charge and promptly scored his first Premier League goal to earn the Londoners a draw at Newcastle. He then went on to start against Burnley in another draw and is likely to feature against Everton later on Sunday.
The two-time England cap made 12 appearances on loan at Cardiff in the second half of last season but still failed to find the net until his strike at St James' Park, while he was given few chances at Old Trafford under David Moyes last year and new boss Louis van Gaal at the beginning of this season.
His 28 minutes of Premier League football for United led many to suggest his career was at risk unless he secured a move away, but this is a theory Warnock disputes to some degree, despite the winger returning to his childhood club for the 2014-15 season.
"I don't think his career is in jeopardy," said Warnock. "I wouldn't say we need to save his career, we just need to get games under his belt now and he needs to put himself back in the shop window (for England).
"To do that he has got to consistently be good, week in, week out. That has to be his aim this season.
"He is in that age-group that is breaking into the England squad. He is definitely looking at all these young lads - they deserve it, they have worked hard and done consistency well. It will motivate him.
"The problem has been he has not had enough games. He needs games, last week he ran out of steam a little bit but he is putting the work in on the training ground. Ability and confidence is nothing he has ever been missing."
Warnock has been impressed by Zaha's attitude since he returned to Selhurst Park, and revealed that the young English forward was eager to convince Louis van Gaal that he has a future at Old Trafford.
"He has come here to try and convince the (Man United) manager that he works for that he is good enough to give him a go - that is his aim.
"His attitude has been spot-on since I met him - there were three or four clubs after him and we got him, but his intention is to try and go back there and get in the team and I think that is great for the young lad."
