Robbie Brady, the current top scorer in the Republic of Ireland Under-21 team, believes the Showgrounds crowd have a major part to play in tonight's crucial 2013 UEFA Championship qualifier against Turkey in Sligo (7.30pm).
Noel King's Ireland are sitting in third spot, two points behind Turkey who will complete their campaign tonight. Ireland have two more games left, away to Hungary and Italy next month, so their destiny remains very much within their control.
Italy are favourites to finish top of Group 7 to secure a play-off place and Ireland could join them with a strong conclusion to the campaign.
Only the four best runners-up across the 10 groups clinch a play-off berth and King reckons seven points from a possible nine remaining would be sufficient.
With players like Manchester United talent Brady in his ranks, there's every reason for King to be optimistic.
Alex Ferguson recently handed the 21-year-old his first-team debut on pre-season and the player is determined to continue his momentum in the north-west this evening.
"This is the big game for us," said the Dubliner.
"To have it in our hands at this stage is all we could have hoped for and, with the big crowd in Sligo continuing to support the team, we'll do everything to get the win.
"Like me, the rest of the lads have a big incentive to get through the next few games and push on towards qualifying."
"The crowd in the Showgrounds have been fantastic in all the games that we've played there.
"The players really appreciate it, especially against Italy in June when they really helped us get back into that game. Hopefully we'll have another massive crowd on Tuesday and create a great atmosphere."
UCD midfielder Paul Corry has received a late call-up to the squad. Aston Villa midfielder Samir Carruthers was forced to withdraw from the vital clash after sustaining an ankle injury in training.
It's the latest selection headache to hit the Irish squad in recent days following a number of injury withdrawals from the initial 22-man squad.
"It's never nice when somebody is forced out by injury and it's disappointing for Samir as he's been in very good form at Aston Villa this year and was looking very sharp," said King.
"Players are always disappointed to be ruled out through injury but it opens the door for somebody else to step up and make a contribution."
He added: "This is a massive game for us. It would make our chance of qualifying for the play-offs considerably easier if we could secure the three points on offer so that's what we're aiming for.
"Turkey are the only team to beat us in this group and that was a very tight affair. I would imagine it could be a similar situation but we're looking forward to the challenge."
Tickets are available from the Showgrounds.
