A number of QPR's first-team players are out of contract in the summer, leading Hasselbaink to predict a summer of transition at Loftus Road.
QPR manager Jimmy Floyd Hasselbaink says there are likely to be a number of changes at Loftus Road over the summer, with several players out of contract at the end of the season.
Karl Henry, who scored the only goal of the game in Saturday's 1-0 win over Bristol City, is one of those players whose current deal is about to expire, along with Junior Hoilett, Alejandro Faurlin and Clint Hill.
With so many players poised to leave West London, Hasselbaink admits the summer is likely to be a transitional period for his team.
As reported by Get West London, he said: "We've got some good characters here at the club and we have a base and we now want to work from that base.
"There are going to be some changes at this club, but we also have to understand that it's not going to be about only throwing money at it.
"We want to make sure that we are all going in the same direction and are a good team, not just individuals."
One change the Dutchman is particularly eager to implement is to make his team more entertaining, although he admits that the rigours of the Championship can often have an effect on the style his team adopts.
He said: "Style is always something we want to play with, but it has to be possible - you are not going to win every game in style.
"Sometimes you have to dig in and battle, but we want to play with a style where we pass the ball and create chances."
The likely upheaval to Hasselbaink's squad is not the only major change set to be introduced at the club, with Rangers also recently unveiling a brand new badge ahead of next season.
