Northern Ireland boss Michael O'Neill downplayed suggestions he could be interested in any possible managerial vacancy with Scotland by insisting he had "not given it a second thought".

Some pundits have suggested O'Neill would be a perfect fit for the Tartan Army should Strachan's three-year tenure be ended following a poor start to their World Cup qualifying campaign.

Those tipping Edinburgh-based O'Neill for the post have admired his work in turning around Northern Ireland’s fortunes, culminating in a first ever European Championship finals appearance in the summer.

Northern Ireland also well placed after four matches of the qualifiers for Russia 2018 and currently sit second in Group C.

However, having signed a four-year contract extension back in March, O'Neill insists the possibility of switching jobs at the international level has not entered his mind.

Asked if Northern Irish fans should be worried about his links with the Scottish post, O'Neill replied: "No, I don't think so.

"First of all, there's someone in that job who I have a huge amount of respect for, who is a manger I played under (at Coventry).

"It's probably the fact I live in Scotland is a bigger driving factor of that than anything else. I haven't given a second thought to that at all. I'd rather not give a comment on that situation at the minute to be fair."

O'Neill, turning his attention to his current squad, said of the success they are enjoying: "A lot of our key players are 30-plus, but maybe what that gives us in our favour is they don't want this to stop, they want it to last as long as it can."

"When you've played a lot of international football you want it to last as long as possible, because they have played through some dark days as well.

"If you get them (memories) at the end of your career you remember it a lot more fondly.

"The legacy hopefully this group of players leave is a positive one, not only from the Euros but going forward, because they genuinely want to go to a World Cup and push for that and be in contention for that."

Meanwhile, veteran goalkeeper Roy Carroll is back in the Northern Ireland squad for the friendly with Croatia on Tuesday after Michael McGovern returned to Norwich.

Linfield stopper Carroll, 39, has not been a part of Michael O'Neill's groups since Euro 2016, with McGovern, Alan Mannus and Trevor Carson the three keepers of choice.

However, with McGovern back in England for assessment on a minor problem and Carson having sustained a dislocated finger while playing for Hartlepool on Saturday, Carroll has been drafted back as cover for St Johnstone's Mannus.

QPR striker Conor Washington is another who will take no part against the Croats at Windsor Park after a groin injury forced him to withdraw prior to Friday's 4-0 World Cup qualifying win over Azerbaijan.
