And Warnock, who has been in interim charge of the R’s for the past three weeks, has offered some advice to his successor.
Warnock claims that QPR’s squad only needs a couple of additions in January to mount a play-off push, and he has urged Hasselbaink not to completely reshape his ranks.
"I think the squad only needs tweaking," he said.
"There are probably a couple of positions that need a bit more strength in depth but there is a great chance of getting in the play-offs. And once you get in the play-offs, anything can happen."
QPR do have one of the strongest squads in the Championship on paper, but so far many of their players have performed below expectations.
The R’s are five points off the play-off spots as things stand, and Hasselbaink has a big task on his hands to guide them up the Championship table.
Hasslebaink’s managerial career so far has been highly impressive, though, and if he can have as much success at Loftus Road as he has at Burton Albion, then his appointment will be celebrated.
Hasselbaink has guided Burton up from League Two to the top of League One in his first managerial job in English football.
