The 68-year-old spent two seasons at Town during the mid-1990s, guiding the side to Division One via the 1994/95 Play-Offs before returning to West Yorkshire in 2012 for an under whelming spell in charge of Leeds.
Both West Yorkshire sides are currently firmly entrenched in the top six and despite Warnock's previous allegiances to both clubs, the veteran manager gave an unexpected response when discussing the promotion candidates on TalkSport.
Currently Huddersfield Town lie third in the table, Reading FC fourth with Leeds and Sheffield Wednesday making up the final two places.
However, seventh placed Fulham FC are pushing the Owls close for the final Play-Off spot, currently two points away from the top six.
"I think it could be whichever one of those two, myself. I think they could win the play-offs, Sheffield Wednesday or Fulham" Warnock told the popular radio show.
"Fulham are a good side but they’re not so good on the defensive side of the game so it’ll be interesting.
“I think those two teams have got enough in the play-offs with what they’ve got, but you’ve got to take your hat off to the other lads.
“I mean, (Leeds United manager) Garry Monk’s (been) fantastic after a bad start, and Huddersfield... wow, you know. It’s unbelievable."
Warnock could also have a say on the final reckoning with his Bluebirds travelling to both Wednesday and the John Smith's Stadium before the end of the season.
