Republic of Ireland defender Damien Delaney has denied asking manager Martin O'Neill for a regular place and says he has "no issue" with Roy Keane.
The Crystal Palace player was omitted from a 37-man squad on Tuesday, making the last of his nine appearances in a friendly defeat by Turkey last year.
O'Neill stated that Delaney had not been willing to return unless he was guaranteed a place in the team.
Delaney responded: "I never asked for a regular starting position".
The Premier League regular previously admitted having a rocky relationship with Keane when the Republic's assistant manager was his club manager at Ipswich.
Issuing a statement through social media, he insisted he has "no issue with Roy Keane and shook his hand this summer at a Cork City European match".
When explaining Delaney's omission from his training squad on Tuesday ahead of next month's 2016 Euro qualifiers against Gibraltar and Georgia, O'Neill said he did not think the player would return unless guaranteed a place in the side.
"I cannot guarantee anybody a place in the side," he said.
"I do not think at his age if he wants to be running as just being part of this squad. I cannot guarantee that to almost all the team."
Delaney appeared to signal the end of his international career and said: "I know that at the age of 34 the future of Irish football does not lie with me".
"The rigours of Premier League football and the 24/7 dedication required takes its toll so I look on the international break as a chance to recover.
"I spoke to Martin O Neill and contrary to his recent comments, I never asked for a regular starting position.
"I did, however, disagree with certain aspects which out of respect to Martin and the national team will remain private."
