Matt: Watching Costa Rica v Northern Ireland on BBC Football website - Safe to say I'm at a loose end today...!

We're glad you're enjoying our coverage Matt!

Stuart Dallas spots a channel to run through on the left and he's only stopped by a cynical tug of the shirt. Michael O'Neill will be pleased enough with this opening.

Chance! Johan Venegas sprints in behind the Northern Ireland defence and lays the ball back, Joel Campbell runs on to it and curls a shot well wide from the edge of the area.

It's a very decent atmosphere in these early stages.

Nice! Northern Ireland go close as Charlton man Josh Magennis wins a flick on and finds his strike partner Liam Boyce surging through the middle, he opts for the first-time lob and never really gets hold of it. But that was a chance - Keylor Navas was well out of position there.

Costa Rica win a corner, it's knocked to the edge of the box for Sunderland left-back Bryan Oviedo to line up but his shot is duffed well wide. No danger for Trevor Carson.

A reminder that it's just gone 11am in San Jose. A strange old time for an international match but there's a very decent crowd in.

Aaron Hughes is seven games away from breaking Pat Jennings' caps record for Northern Ireland. Incredible longevity from the now Hearts man.

Nothing like a delayed kick off - away we go!

Costa Rica play England at Elland Road on Thursday night of course. Real Madrid goalkeeper Keylor Navas has been presented with a massive golden glove, not unlike a Gotcha from Noel's House Party.

Strong, strong work from our graphics team here.

No expense spared. Apologies to Liam Boyce, who missed the cut for some reason. Lee Hodson will hopefully be on the pitch for at least some of the game...

Costa Rica's only win in their last seven matches came against Scotland.

They face Brazil, Switzerland and Serbia in Group C in Russia.

It's a 9/10 from me for the Costa Rican anthem. Top class.

Around 150 Northern Ireland fans are in attendance by all accounts. A superb, if entirely bonkers, effort.

You can now watch this game LIVE at the top of the page or on the red button.

Blazing sun as you'd expect at the great looking Estadio Nacional in San Jose.

Costa Rica: Navas, Gonzalez, Duarte, Acosta, Oviedo, Gamboa, Guzman, Borges, Campbell, Colindres, Venegas. Subs: Smith, Ruiz, Wallace, Azofeifa, Calvo, Tejeda, Pemberton, Waston, Matarrita, Moreira, Urena.

Northern Ireland: Carson, Hughes, McAuley, Jonny Evans, Hodson, McNair, Dallas, Boyce, Corry Evans, Cathcart, Magennis. Subs: Conor McLaughlin, Ferguson, Whyte, Smyth, McCartan, Lavery, Peacock-Farrell, McCullough, Thompson, Hazard, Ryan McLaughlin.

Let's be honest, there are worse away days to take on.

I wouldn't say Aaron Hughes - who starts in defence tonight - has had a lengthy international career, but he made his debut two days after Titanic won 11 Oscars in March 1998...

This game is being played at 11am local time, which could mean it gets very, very, very hot indeed.

If you're a fan of perspiration over inspiration you're going to enjoy watching the NI midfield trio of Evans, McNair and Evans shuttling about.

Here's the Costa Rican XI.

Real Madrid goalkeeper Keylor Navas starts for Los Ticos fresh from winning a third Champions League, while Joel Campbell, Bryan Oviedo and Cristian Gamboa - who have all played in the Premier League - start, with ex-Fulham midfielder Bryan Ruiz on the bench.

Northern Ireland held Panama - who face England on 24 June live on the BBC - to a goalless draw earlier in the week.

Will we get some goals this evening?
