Richard Dunne admits his international future is hanging in the balance after the Republic of Ireland's poor showing at Euro 2012.
The defender was part of a campaign in which they were the first team to be knocked out having lost every game and included a heavy defeat to eventual winners and defending champions Spain.
Having spent a summer reflecting on the tournament the 32-year-old has yet to decide on whether to hang up his international boots or aim for a century of caps.
Dunne will make a decision in the next few weeks after talking the matter over with his Aston Villa boss Paul Lambert, who himself played 40 times for Scotland.
"Retirement has crossed my mind a few times," said Dunne. "It's easy after a tournament, the way it has gone, to make a rash decision and say 'that's it'.
"But I just have to think about things. I was basically waiting to get back into training with Villa and then have a think, see how I feel.
"It's a hard decision, because it (playing for Ireland) is something I love doing, and I had a chat with Paul Lambert about it and asked him about it.
"He said it has to be down to me because if I'm not happy with the decision and I regret it, then it's no good. I've already spent four weeks thinking about it and still can't decide."
The defender still has a few weeks to make up his mind as Ireland do not kick-off their qualifying campaign for Brazil 2014 until the start of September.
