The Republic of Ireland face Portugal in a World Cup qualifier this evening.
Here's everything you need to know about the game.
Where is the game and what time is kick-off?
Ireland’s Group A World Cup qualifier against Portugal kicks off at 7.45pm (Irish time) at the Estadio Algarve.
Where can I watch it?
The game will be live on RTÉ 2 with coverage starting at 7pm. Sky Sports' coverage starts at 7.30pm.
How is the group poised?
It's been a nightmare start for Stephen Kenny's side. In the opening round of qualifiers in March Ireland lost 3-2 to Serbia in Belgrade before a 1-0 loss to Luxembourg at the Aviva Stadium.
Portugal are on top of the group with seven points after two victories and one draw.
Serbia also have seven points, so realistically Ireland will need at least a draw from tonight's game to keep any hopes of qualification alive.
Team news
Ireland are missing Jason Knight, Enda Stevens and Callum O'Dowda due to injury.
