The Canadian has reportedly agreed a deal with the west London club over a potential move to Borussia Monchengladbach, which would have seen Hoilett leave Ewood Park for free.
By choosing another English club, Hoilett has ensured that Rovers will receive compensation and Kean hopes that they will not be sold short, hinting that he may look to bring in players from Loftus Road as replacements.
"QPR might make us an offer, if not it might go to a tribunal," Kean told The Sun. "We were always hopeful he would go to a club here because the compensation would be greater.
"Manchester City got a chunky figure when Daniel Sturridge went to Chelsea. We have had Junior for a long time and we developed him and put a lot of time and effort into him.

"I am sure that will be reflected when the time comes.
"There are plenty of good players down there [at QPR]. But we are finding out that clubs like to keep their best players."
The 44-year-old also admitted his disappointment that the club had not been informed that Hoilett was in discussions with the Hoops.
"We feel we have been a big part of his development," Kean added. "It would have been nice to get a call.
"We had monthly meetings with his dad and he said he was keeping his options open. His dad is his agent and has been all around the world looking for offers."
