Warnock: New signings the key
Mark Hughes, the former Manchester City, Wales and Fulham manager, has held talks over succeeding Warnock at Loftus Road and is on the brink of agreeing a deal with the R's.
However Warnock, who was sacked on Sunday, is convinced the area which needs the most attention is the calibre of player at QPR.
He was planning to overhaul his squad this month, and was confident his signings would lift the London club well clear of relegation danger.
The rebuilding task will now be passed over to the next manager, who reports suggest will be given plenty of backing in the transfer market.
Warnock told The Independent: "Will a new manager make a difference? Not as much as new players will.
"If you haven't got the players you can't win games, that's another fact of life in football management.
"I just wish I had the chance to bring in the ones I wanted, both in the summer, and this month."
Warnock claims more experienced club owners would have realised "there would have been no problem securing a Premier League future" had he been given the go-ahead to make the signings he wanted.
"But no doubt the chairman has had a string of agents in touch telling them their man could do a better job," Warnock added. "It looks like it might be Mark Hughes, though I heard around Christmas they were thinking of (Gianfranco) Zola and (Ray) Wilkins."
