Steven Davis' nice diagonal ball is just out of reach of Liam Boyce as Northern Ireland start to go a bit more direct.

Paddy McNair drives in a corner towards the near post, Craig Cathcart meets it but his header loops over the bar. It's been over four years since Northern Ireland last scored an away goal in the first half of a game and they are yet to test Estonia keeper Sergei Lepmets in this match.

We have to get back to the way we started on the game. We have to get Lewis on the ball and get attacking up the left wing. It's early days yet though.

Work to do for Northern Ireland. They came here on the back of excellent preparations according to Michael O'Neill but they've largely been second best so far.

No major surprises so far.

Armenia are 2-0 up against Liechtenstein in Group J. Willi Orban has put Hungary 1-0 ahead in Azerbaijan in Wales' Group E.

Moldova lead Andorra 1-0 in Group H.

Paddy McNair's charge up the right is halted when Mattias Kait gets across to the put the ball out for a throw. Michael Smith attempts to get it into the box but Estonia clear.

I am warming to this playing from the back but it has to be done right. I know the England team was criticised for doing it but you have to make the right decisions.

Gavin Whyte's pace enables Northern Ireland to quickly get the ball upfield after that Estonia attack but the hosts get back quickly to shut the door on any opportunities in the box.

Craig Cathcart is called upon again as Jamal Lewis is beaten to the ball in the air by Konstantin Vasslijev, whose knockdown into the box is put behind by Cathcart, who then heads away the corner.

Crucial interception by Craig Cathcart. Konstantin Vassiljev gets the better of Jamal Lewis on the left and whips in a dangerous low ball but Cathcart gets to the ball first and his attempted clearance loops up into the air before being collected by Bailey Peacock-Farrell.

It's been over 10 hours since the travelling Northern Ireland fans last saw a goal scored by their side away from home. Will that long wait come to an end today? The early signs are promising as they are keeping Estonia in their own half.

Another Northern Ireland attack as the long throw of Stuart Dallas is deployed this time. The Leeds man aims for Jonny Evans but the hosts sweep up the danger.

Positive start by Northern Ireland, who put Estonia on the back foot immediately. Jamal Lewis' cross is deflected behind for a corner, which Michael Smith sends to the far post but the referee blows for an infringement.

We're under way!

Now there's a minute's silence for former Uefa president Lennart Johansson, who died earlier this week.

The players are caught out as the choir sing a third verse after about a 10 second pause following the second verse.

It led to the slightly awkward moment of all the fans cheering assuming they had finished before having to sheepishly fall silent to let them sing the final verse. It sounded good, though.

It's national anthem time and something a bit different from the hosts as Estonian Television girls' choir sing their country's anthem.

It's a first competitive start for Oxford United midfielder Gavin Whyte, so a big chance for him to make an impression.
