Aiden McGeady is expected to be targeted by sections of the home crowd in the European qualifier tonight, but looked in high spirits on the flight to Glasgow yesterday.
The result tonight could go a long way to deciding the fate of both sides in such a close group.
Martin O'Neill will have to overcome injuries to Glenn Whelan and James McCarthy and also put Roy Keane's altercation on Wednesday night behind him as the Boys in Green go in search of three points.
Shane Long took a selfie on yesterday's flight to rally the troops.
"Alright lads lets (sic) do this #cheesymcgeady," he posted on his account.
