Northern Ireland defender Gareth McAuley may quit international football after being left out of the squad to face Sweden on 17 October.
Gareth McAuley has made five appearances for N Ireland
"I'll see this campaign out and after that I'll be thinking of the future," said the Leicester City player.
"If I'm going away for 10 days and I am not being involved it frustrates me and it knocks your confidence a bit."
Bristol City winger Ivan Sproule is also considering his future with NI after failing to play in recent games.
Northern Ireland boss Nigel Worthington phoned the 27-year-old at the weekend to break the news that he is not in the panel for the Euro 2008 qualifier in Stockholm.
"It's something I'm not very happy about but I've just got to take it on the chin," added McAuley.
"He's cut the squad back and myself and a couple of other lads are disappointed.
"He just said to keep doing what you are doing at your club and you will get a chance.
"It's very frustrating, especially after watching the performance against Latvia.
"He said he was going to make changes but I didn't even make the bench for the second game (in Iceland)."
"It is very hard going away for 10 days, rushing back and having no preparation for club games, which is not the best for Leicester."
McAuley, who made his Northern Ireland debut against Germany two years ago, captained City in Tuesday night's scoreless draw with Wolves.
