The Stoke midfielder is believed to be available after making just five appearances for the English Championship side this season.
Gary Rowett is obviously preferring other midfield options to Adam – and that means other teams will be on alert to sign the midfielder this term.
One of those to be mentioned most is Hearts, with Craig Levein reportedly keen to sign Adam.
For Adam, that’s a move that may interest due to his relationship with former Scotland manager Levein.
The Stoke man, per scotsman.com, said: “I woke up on Tuesday and I had loads of texts about Hearts.
“I have had no contact with any club in Scotland. I don’t know where it has come from, speaking to people I know, supposedly there is an interest but there has been no contact with me or my agent.
“I had a good relationship with Craig at Scotland and I like Craig as a manager and as a person. He is straight, honest, says it how it is, like me, and sometimes he upsets people.
“He is a good guy, he has done terrifically well but at the moment there is nothing there.
“I’ve had a good career. I have enjoyed it. I have a lot to go and I still have a lot to learn, I like to learn every day.
“Hopefully I go to a place where I will enjoy it and hopefully they enjoy me being there and showing that Charlie Adam is a good player.”
A return to Rangers could also make sense for Adam given his six-year stint there at the start of his career.
Adam made 88 appearances for the Ibrox side before starting a career in England with Blackpool, but insists he’s open to a return to Glasgow to play for Steven Gerrard’s men.
He said: “At the moment I am still contracted to Stoke but I want to play and hopefully there are opportunities during the window to play somewhere.
“The Rangers thing is something that it would interest me. Absolutely. I have been back more times this season than in the last four or five years. I can see it is going in the right direction.
“Steven has obviously put his authority on the club. The players are playing well, playing with an unbelievable amount of confidence.
“The manager has got it on a playing field where it is competitive and what a hell of a result against Celtic in the last game.
“The tails are up, they have momentum but they know it is going to be a big challenge from now until the end of the season.
“But at the moment there is nothing to it. We are talking up something that is not there but everyone knows I started my career at Rangers, I played in front of 50,000 with the pressure.”
Gerrard will be on the lookout for players to strengthen his Rangers team after what has been a successful first half of the season.
But would Adam fit the bill?
