Queens Park Rangers boss Mark Hughes claims he would not stand in Robert Green's way if the keeper wanted to leave the club in January.
The England international only completed a switch to Loftus Road earlier this summer, linking up with QPR as a free agent after seeing his deal run down at West Ham.
He was quickly installed as Hughes' number one, but has now seen that position come under threat from another new arrival.
Brazilian shot-stopper Julio Cesar has been snapped up from Inter Milan and a man with a UEFA Champions League winners' medal to his name is expected to be handed an immediate starting berth.
That will leave Green benched just a matter of weeks into his QPR career, and Hughes appreciates that the 32-year-old may want to go in search of regular games elsewhere.
He said: "That isn't my concern. That may concern Rob in terms of his international standing but from my point of view I have got to make sure we are strong as a club.
"If in the future any of my keepers came to me and said they felt their future lay elsewhere then we can have a conversation about that and make a decision that benefitted everyone.
"But at the moment it's early days and the challenge is there for all my keepers.
"It's a difficult situation for Rob but the opportunity to bring in Julio Cesar came very quickly and it's one that we felt as a club we couldn't ignore.
"On a football level and a business level, we needed to do it because you don't get opportunities like that very often."
