Martin O'Neill has named his starting team to face Moldova this evening.
David Meyler leads the side for the 7.45pm clash.
Only three points will do for the Republic of Ireland tonight if they are to keep their hopes of World Cup qualification alive.
They play host to Moldova at the Aviva Stadium on the back of a poor 2017 which saw automatic promotion slip away.
Meyler is joined by Wes Hoolahan, Jeff Hendrick, Shane Long and Ciaran Clark for the first round of World Cup Qualifiers.

Draws with Austria, Wales and Georgia as well as a defeat to Serbia means Martin O'Neill's side can not afford any more slip ups.
Ireland must claim wins tonight and in Wales on Monday, while also hoping Scotland fail to win away to Slovenia on Sunday, if they're to sneak into the playoff spots.
There is no Robbie Brady or James McClean tonight due to suspension, and with Jonathan Walters injured a number of players could be in line to make their debuts.
Manager Martin O'Neill says he has seen before that his team can thrive under this sort of pressure.
The subs bench comprises Doyle , Elliot, O'Shea, Keogh, Whelan, McGeady, O'Kane, Maguire, Hourihane, Hogan, K. Long, Arter.
The FAI are also using the match to raise awareness of homelessness.
In the official match programme, four pages were reserved for a special edition of The Big Issue, which included a feature on Thomas Morgan, manager of the Homeless World Cup team, as well as pieces on the Late Nite Leagues and the Irish Street Leagues.
Match tickets were also given to members of the Homeless World Cup squads - men's and women's - who did brilliantly in the recent tournament in Oslo.
Also, in a link up with Dublin Simon Community, the FAI supplied a number of premium level tickets as well as kids goodie bags to families who have recently been displaced from their homes.
"The FAI has a long-standing relationship with organisations working to tackle homelessness around the country with the Irish Street Leagues affiliated to the Football For All programme and several other projects undertaken by the Intercultural Department," the FAI said.
