BBC Scotland's Alasdair Lamont at Celtic Park

'Home of Scottish football'published at 18:36 GMT 14 November 2014
Ireland sit second in the Group D table, behind Poland on goal difference, with Scotland three points behind in fourth.
Strachan is confident the Tartan Army will turn Celtic Park into a real home from home for Scotland players.
The match is being played at the stadium - Scotland hosted Georgia at Ibrox in their previous home game - because the national stadium at Hampden was converted to an athletics venue for the Commonwealth Games.
"We will turn Celtic Park into the home of Scottish football," said Strachan.
Image source, PA"We had a lovely taste of it at Ibrox [against Georgia]. I thought the atmosphere there was great as well and I thought the Scottish fans turned Ibrox into the home of Scotland for the day and we'll do that [against the Republic of Ireland].
"Everything's been built up over the last couple of weeks. It has become a hot game."

Gordon Strachan and Martin O'Neill return to their former stomping ground with the aim of securing three valuable points.
