Richard Dunne has admitted that being asked about Stephen Ireland's international future irritates members of the Republic of Ireland squad.
Ireland has not played for his country since falling out of favour with Steve Staunton 12 months ago.
Giovanni Trapattoni has left the door open for him to return but Ireland has insisted he is happy not playing at the present time.
He has refused to rule out a possible comeback and Manchester City team-mate Richard Dunne believes the situation could become increasingly complicated.
"I don't think anything more can be done," Dunne said in the Belfast Telegraph.
"He's 22 now and he's made his decision, he doesn't want to play and that's it.
"What the manager has done is say the door is open and if he wants to come back, then he can come back.
"But I think the longer it goes on, the more difficult it gets. If we get to a stage where next September we're sitting top of the table and looking like qualifying, is it right that he comes back?"
Dunne can understand why some Ireland players get frustrated when asked about someone who is on a self-imposed exile.
He explained: "That's the one big annoying factor of it.
"If he doesn't want to play then fair enough, it's his own choice or whatever, but if we have to keep getting asked about it and answer questions on his behalf every time we turn up then that's annoying.
"He did an interview last week but hasn't really clarified it. Unless he comes out and says, 'I don't want to play for Ireland' then it's going to keep going over and over."
