The 28-year-old left then-Premier League side Blackburn to join Anzhi less than a year ago with the Russian transfer window still open for a fee believed to be around £12.3 million.
Now it is reported that QPR have matched his release clause in a bid to bring the Congo centre-back to England once more, though current boss Guus Hiddink revealed he is unimpressed with Samba flying off for talks without informing the club.
"This is not really good for us," he told Sport-Express. " Samba has been with us for the whole season, he started working with us at the training camp, and all of a sudden the English side has come up.
"Yesterday he flew to England. Unfortunately, we didn’t even have a chance to say goodbye. Everything happened really fast.
"Well, this is a problem that we have to tackle. We have to face the facts. I think we will know the details in the coming days."
Meanwhile, QPR have given Alejandro Faurlin permission to speak to Palermo over a loan move.
The 26-year-old is one a handful of survivors from the Hoops side that secured the Championship title in 2011.
However, Press Association Sport understands the midfielder could now be off to Serie A side Palermo on loan until the end of the season.
Faurlin has been given permission to speak to the Sicilian outfit, although it is understood the deal is not with a view to a permanent move.
