The Republic of Ireland will be expected to board the plane to Germany on Monday with six points in the bag in group D of the Euro 2016 qualifiers.
Martin O'Neill's side host Gibraltar who have only played one competitive game since being admitted as UEFA's 54th member in May of last year.
Gibraltar were beaten 7-0 by Poland last month in front of around 1,200 fans at Estadio do Algarve in Portugal which was the same night Aiden McGeady scored a late goal to give Ireland a 2-1 win away to Georgia.
Everton pair Seamus Coleman and James McCarthy both started in Tblisi last month but both are ruled out due to injury which means O'Neill will have to change things up.
Gibraltar has a population of just under 30,000 and tonight will be their first competitive away game so none of their players will have played in front of such a big crowd.
They had played five friendlies before that Poland game and which included two draws (one was a 1-1 draw in Estonia) and a famous win over Malta in June.
Only four of Allen Bula's squad play their football outside Gibraltar, two of those at Football League clubs in England. Preston North End defender Scott Wiseman and Bristol Rovers midfielder Jake Gosling are part of Bula's squad.
Nine members of squad play for Gibraltar champions Lincoln Red Imps.
Having watched the Poland and Gibraltar game Martin O'Neill had this advice for his players:
Kick off at the Aviva Stadium is 5
Other games in Group D, Scotland and Georgia play at 5.00 at Ibrox.
Poland host World Champions Germany at 7:45.
