QPR manager Jimmy Floyd Hasselbaink
As quoted by the Bristol Post, Hasselbaink hinted he was looking to bring in a striker instead.
"We need to get goals and strengthen in that area (attack), the Dutchman apparently said.
"Bradley Dack is not really a striker. He's a number 10 and we don't need another one of them. We've got [Tjaron] Chery, Nasser [El Khayati] and Ben Gladwin, who we expect a lot from this year. He's come back really well."
Dack was directly involved in 23 league goals for Gillingham last season, which led to him being crowned League One's player of the year.

According to the Bristol Post, City saw two bids for the 22-year-old knocked back last term and remain keen on a deal, with Gillingham said to rate the Londoner at £2.5 million.
Palace and Celtic are also listed as suitors by the report, with the latter set to lose Stefan Johansen to Galatasaray, according to a report in the Scotsman this week.

Doubts also surround the future of another Bhoys attacking midfielder, Tom Rogic, who is out of contract next summer and said to be interesting Arsenal among others (Glasgow Evening Times).
Should the pair depart than Dack would be an ideal replacement on paper.
