Chelsea defender Tomas Kalas is unhappy on-loan with FC Koln.
The People says the 21-year-old Czech Republic star was loaned out to Koln this season but has struggled to get in the side.
He is frustrated by his lack of opportunities and is now looking for a way out.
QPR have been alerted by the situation as they aim to bolster their defence and believe a deal may be possible.
They want Chelsea to call him back from Germany - and then loan him to Rangers.
