The R’s brought in a number of new faces during the summer transfer window, but Warnock omitted a large volume of them during his time in temporary charge.
The 67-year-old only started three of QPR’s summer recruits in his final match at the helm against Reading, as he helped the side claim a 1-0 victory.
And Warnock said: “I don't think many of the summer signings were at Reading. I've gone with a group of players I think can do well in the Championship and moulded that into a very good team.
“They have to believe in themselves. It's a great job for Jimmy to take on. I bet he can't believe his luck taking over this group of players. It's a special club.”
Warnock has transformed QPR’s form during his brief time at the helm, and made them a much tougher team to beat.
The R’s were leaking goals over the early part of the campaign, with Chris Ramsey failing to organise their defence sufficiently.
However, during Warnock’s four matches in charge, QPR conceded just one goal, giving Hasselbaink a strong platform to build upon.
The former Burton Albion boss inherits the QPR squad with the team currently sitting in 12th place in the Championship table.
Hasselbaink’s first match in the dugout at Loftus Road comes this weekend, when QPR host promotion-chasing Burnley.
