Former Northern Ireland defender John O'Neill

"The fact that Michael McGovern is Northern Ireland's star player so far is a reflection of the play. It's a better game than I thought it would be. The players and the managers may be getting something out of it but there's not much in it for the rest of us and the fans.

"Stuart Dallas has put in as good a left-sided performance as I've seen from a Northern Ireland player in a long time. On this display I'd be tempted to throw him in against Finland."

Pepper Jack on Twitter: "Why are @ScottishFA trying to pass it into the net? This is going to be a dull 0-0. Usual tedious friendly outcome. Boring. #bbcscotfootball"

Hotel&restaurant PR on Twitter: "#bbcscotfootball Playing with one up front at home! What is Strachan playing at and what does that say about Scotland's ambition?"

"Michael McGovern is the main reason why it is still scoreless. Michael O'Neill will be the happier of the managers at half-time as Scotland have had the better chances."

"Plenty of positives for Scotland manager Gordon Strachan in the opening half, in particular the performance of Ikechi Anya. Scotland have created half chances, against a well-ordered Northern Ireland side, but there is much for the home side to build on. A sharp, confident finisher could yet come to prominence in this game."

I'm guessing Ikechi Anya knows he is not coming back out for the second half since he was shaking hands with English referee Martin Atkinson on the way off. He won't be the only change at the interval, I'm sure.

Scotland have done most of the pressing but have not been able to find a way past Northern Ireland goalkeeper Michael McGovern, who made a couple of useful early saves.

Shaun Maloney slides a lovely reverse pass through for Steven Fletcher but out comes Michael McGovern to make a good blocking save. The Hamilton keeper has looked very assured this evening.

Anonymous: "Nice cap doffing to history with the Blue Kit for NI. Ireland's original sporting colours. Looks good."

Anonymous: "Re Scotland shirt; I am guessing it's a nod to the Scotland shirt used occasionally in the late 1880's & early 1900's. Something to do with the Earl of Rosebery. Shocked wee Pat Nevin didn't know that!"

Do include your name. We like to credit these pearls of wisdom.

Scotland full-back Craig Forsyth drives an excellent ball across goal from the left and Steven Fletcher gets his legs in a tangle attempting to touch it in. An offside flag is raised, so the miss is not quite as bad as it might have been.

A much-changed Northern Ireland team is looking more comfortable now as they find their shape and the hosts are finding it more difficult to find gaps to exploit.

Northern Ireland striker Will Grigg has been pretty isolated so far and the crowd jeer cruelly as he attempts to gather a long ball over the top, only to kick the ball back into his own face. Ouch!

"The pace of the game has been excellent. There's lots going on and the signs have been positive for Scotland."

ash mccutcheon on Twitter: "#bbcscotfootball good so far kept ball well annoying that it's still 0:0 should be 2:0 Scotland Steven Fletcher off at halftime."

Scotland come again, with Ikechi Anya inevitably involved, poking the ball on for Steven Fletcher to have a dig from the edge of the box. It's firmly struck but the shot is gathered well by Michael McGovern.

Ikechi Anya pounces on a stray pass from Josh Magennis and turns on the after-burners again before rolling the ball into the path of Shaun Maloney, who can only blaze a dreadful, first-time shot high into the Glasgow sky.

"Impressive passages of play from Scotland. Matt Ritchie has shown promise turning into his left foot, while the quick and busy Ikechi Anya has the beating of Paddy McNair, the Northern Ireland full-back. If the home side can take advantage of their wide players, they can turn possession into chances."

Daniel Lafferty lumps the ball forward and there is hesitancy in Scotland's central defence, allowing Chris Brunt a sight at goal, but Gordon Greer recovers to make the block.

James McArthur turns up in a central position this time as Scotland counter at pace. His pass sends Ikechi Anya scurrying into the box but the final shot is wretched, skewing away from goal.

James McArthur slings in a cross from the right as Northern Ireland defender Daniel Lafferty sends a back-heel in his direction. The ball is just too high for Scotland striker Steven Fletcher and Michael McGovern punches clear.

"Ikechi Anya is on fire. He's going on the outside, then cutting inside. The Northern Ireland left-back, Aaron Hughes, just doesn't know how to handle him."
