Caulker was out on loan at Premier League clubs Southampton and Liverpool last season.
The 24-year-old central defender has started pre-season training with QPR, and the London club’s manager has been impressed.
Hasselbaink has made it clear that he wants Caulker to be part of his QPR squad for the 2016-17 campaign.
“Steven Caulker has come back absolutely magnificent,” Hasselbaink told West London Sport. “That’s not a player I’d want to let go and not a player I see going. He’s going to stay with us.
“I do not want to let him go. He can help us achieve what we want to achieve. He’s a part of my plans. If it’s up to me, I don’t let him go. How Steven Caulker has come back and has trained in the last two weeks, I’d prefer to keep him.”
Bad news for interested clubs?
Caulker has been linked with moves away from QPR this summer, but Hasselbaink’s comments suggest that he will remain at the London club next season.
As initially reported by Get West London and later cited by The Daily Record, Scottish Premiership giants Celtic are interested in signing the 24-year-old centre-back in the summer transfer window (click here to read more).
Last month, The Express & Star claimed that Premier League side West Bromwich Albion are interested in Caulker, while back in May, The Shields Gazette credited Newcastle United with interest in the defender.
Hasselbaink’s comments suggest that Celtic, West Brom and Newcastle will all have to look elsewhere for a defender, as Caulker appears to be staying put at QPR.
