Euro 2016 Qualifying: All eyes turn to Celtic Park derby

Martin O'Neill is returning to Glasgow with Republic of Ireland

A look at the squad selections and upcoming matches of Northern Ireland, Republic of Ireland, Scotland and Wales...

Northern Ireland

Qualifier: Romania (away, November 14)

Michael O'Neill's men have confounded every expectation to make the most impressive start of all these teams, opening with three victories: at home to Faroe Islands and away to top-two seeds Greece and Hungary. To end the year on top of Group F, they must avoid defeat to the only other unbeaten team, Romania, who are judged 1.654/6 favourites.

As far as selection is concerned, Kyle Lafferty - who has scored in every game - is available, Chris Brunt is back and Jonny Evans remains absent, though his Man United teammate Paddy McNair is involved for the first time.

Republic of Ireland

Qualifier: Scotland (away, November 14)
Friendly: USA (away, November 18)

Republic of Ireland's 2-1 triumph in their Group D opener in Georgia was edgy, with Aiden McGeady bailing them out on a day when they were wobbly, yet their October efforts were practically perfect, following a 7-0 destruction of Gibraltar with a last-gasp equaliser in Germany. Consequently, they co-lead with Poland, but Germany and Scotland are three points behind as they travel to Celtic Park.

The Boys in Green have some injury problems to deal with. Marc Wilson and Glenn Whelan, both starters at Schalke, are out and James McCarthy may follow. However, Seamus Coleman is back and Ipswich's David McGoldrick and Derby's Cyrus Christie have received call-ups, perhaps more so with USA in mind than Scotland.

Scotland

Qualifier: Republic of Ireland (home, November 14)
Friendly: England (home, November 18)

Gordon Strachan's side have begun soundly, losing by one goal in Germany, beating Georgia and holding Poland in Warsaw, though the fact that Poland and Republic of Ireland actually took points off the World Cup winners has slowed their progress. The way to remedy that is by overcoming Republic of Ireland in a match that Strachan admits is bigger than the ensuing England friendly.

Their box of tricks is relatively full, with their main shortcoming occurring at right back where both Alan Hutton and Phil Bardsley are sidelined, and they are rated 2.466/4 favourites for the clash with Martin O'Neill's Group D joint-leaders.

Wales

Qualifier: Belgium (away, November 16)

The outlook is promising for Wales as they enjoy the view from atop Group B, but overconfidence would be premature given that they have pretty much done the bare minimum, defeating Andorra 2-1 away and Cyprus 2-1 at home and drew with out-of-sorts Bosnia in Cardiff. A trip to Belgium represents their toughest challenge, yet they earned a point there in World Cup 2014 preliminaries.

At least, after the lengthy injury list which accompanied the October fixtures, they are in better shape for this one, with Premier League performers Aaron Ramsey, Joe Allen and James Collins all fit again for an encounter in which their nation are 14.013/1 outsiders.
