Portsmouth forward Ronan Curtis, formerly of Derry City, comes on for his Republic of Ireland debut. Callum O'Dowda is replaced.

Kyle Lafferty is kicking a ball on the pitch at half-time - he had the two-year anniversary of his last Northern Ireland goal on Sunday.

Not long until the second half now. I'm looking forward to the constant rolling substitutions after the break. *rolling eyes emoji*

No goals to show for it, but it's been Northern Ireland's half in Dublin.

Stuart Dallas has been the star of the show so far and has been getting in behind the home defence throughout the half.

The Leeds United winger set up the best chance of the opening 45 minutes, squaring cleverly to Gavin Whyte but he saw his shot well saved by Darren Randolph. He also went close himself twice as the visitors got on the front and took the game to their hosts.

Shane Duffy missed the best chance for the Republic, heading into the ground and making it easy for Bailey Peacock-Farrell to save.

It will be interesting to see what changes each manager makes from here, but there's no doubt which boss will be the happier so far.

Think we're following the wrong friendly here...

Austria and Bosnia are goalless at half-time in the Nations League - Northern Ireland will be relegated unless Bosnia win that one.

The Republic of Ireland could be relegated tomorrow when Wales play Denmark.

George Saville takes the corner, it goes across to Steven Davis, who squares it back to Michael Smith...

And the Hearts man fizzes one just over from at least 25 yards.

NI end the half on the attack, John Egan heads out Jamal Lewis' cross for a corner.

We're into injury time now, two minutes added on.

Stuart Dallas picks out George Saville who shoots well over from the edge of the box. Those two Northern Ireland players have linked up well today.

James McClean pushes Michael Smith and has his head in his hands as the referee blows for a free-kick.

Not too long left until the break.

Usual captain Seamus Coleman is wearing the armband now than Glenn Whelan is gone.

The Republic lose the ball, NI break, Steve Davis picks out Stuart Dallas who charges forward and then forces a diving save from Darren Randolph.

A good NI attack comes to an end as Jamal Lewis' low cross is cut out.

"James McClean, he's one of our own" sing one set of fans. Not sure which one...

Robbie Brady's free-kick is headed out... straight to James McClean, who volleys well over the bar.

I can't even imagine what his celebrations will be like if he scores.

Glenn Whelan's farewell lasts only 35 minutes. He comes off to a standing ovation as Aston Villa team-mate Conor Hourihane takes his place.

I wonder whether Wayne Rooney will get longer for England today.
