Seven Championship players in the Republic team, five in the Northern Ireland one.

James McClean really is getting jeered every time he gets the ball. It's pretty intense.

Not sure if Jamal Lewis is trying to score from this corner, but Republic defender John Egan chests it wide at his near post.

Northern Ireland have a corner, Jamal Lewis plays it short, then gets it back and his follow-up cross is turned behind for another corner.

It was pretty much inevitable, but probably worth noting James McClean has been booed on both his first two touches by the Northern Ireland fans.

James McClean is booed by the away fans as he gets on the ball for the Republic of Ireland. More boos than you can shake a stick at in Dublin.

I'm going to say something. I hope it won't shock you too much. But the ball has been in the air for about half the opening 90 seconds.

Under way in Dublin

Put 'Em Under Pressure, the Republic's 1990 World Cup tune bangs out on the speakers.

A classic football anthem to be fair.

A reminder of the line-ups...

Was surprised at quite how loud that booing was. It's 2018 guys.

A lot of boos and whistles for God Save the Queen. You can barely hear Northern Ireland's anthem under the jeers.

Both sets of players are out now and Irish President Michael D Higgins is shaking some hands.

Who's buying these?

We will also bring you goal updates from Austria v Bosnia-Herzegovina in the Uefa Nations League, a game with big repercussions for Northern Ireland.

Northern Ireland are out of play-off contention and, like the Republic, need two results to go their way if they are to stay up.

If Austria avoid defeat at home to Bosnia-Herzegovina tonight, then Michael O'Neill's side are relegated.

If Austria do lose today, then Northern Ireland must beat them by more than one goal in Belfast on 18 November to survive. A three-goal Bosnia win over Austria would mean NI could go through with a 1-0 victory.

Fans from each country exchange tops at pitchside in recognition of the award the Northern Ireland and Republic of Ireland won for their 'performance' at Euro 2016.

It's been a week of both football associations coming together in joint initiatives, but it's nearly time to get the ball out and get the match started.

Both O'Neills have been talking to Sky Sports.

NI boss Michael: "We'll try to win the game. It's always tough away from home.

"Liam Boyce played very well in Bosnia. So he gets the nod again tonight.

"We've created a lot of chances both home and away and feel slightly aggrieved we haven't taken anything in the Nations League.

Republic boss Martin: "Great boost [having players back from injury]. It's nice to see Coleman and Brady back. We'd like to be competitive and win the game if we can - and get through trouble free. Players are playing for places."

Northern Ireland boss Michael O'Neill hopes his team can turn some recent unlucky defeats into positive results in this week's games against the Republic of Ireland and Austria.

"There's going to be an edge. The players are very familiar with each other," added captain Steven Davis.

"With the way results have been for both teams in recent times, it's an important game for both teams."
