The giant French-Congolese centre-back has made 82 league appearances for Rovers - netting six goals - since arriving from Hertha Berlin in 2007.
Despite the defender being contracted to the club until 2012, Samba has been linked with a move this summer, with City, West Ham and Everton all reportedly interested in acquiring him.
And the 25-year-old - who has featured 20 times for the Republic of Congo - has fuelled speculation that he is destined to leave during the close-season after refusing to rule out a move.
"I am still at Blackburn so I can't comment," he said in The Sun.
"Whoever wants me will need to talk to Rovers. I'm calm and waiting."
Should Samba swap Ewood Park for Eastlands, he will become the second Blackburn player to be reunited with ex-Rovers boss Mark Hughes in as many months, after striker Roque Santa Cruz joined the Blues for £18 million.
