Dave Bell's side are joint top of Group 4 alongside Hungary and the two teams meet on Saturday to decide who will go through to the finals tournament in Czech Republic this summer.
A win over Serbia, who are hosting these Elite Qualifying Round games, and a draw with Scotland has given Ireland the confidence that they can complete their objective and top the group.
Defender Sabhdh Doyle insists there is a positive atmosphere amongst the squad ahead of the game in Gradski Zemum, Belgrade. And that is something that they must make the most of.
"If we play to our potential then we believe that we can win the game," states Doyle, who has been a key player with this team for the last two years.
"We are a very good footballing team and we feel that we can match up to anyone at this level. We just have to play our game. We have to set the tempo and put them under pressure."
The months of preparation under Bell's stewardship have brought Ireland to this stage and the players are determined to play as a team in order to overcome the final obstacle.
Galway native Doyle admits that clinching qualification would be the ultimate reward for their hard work. However, she is fully focused on putting in one more big shift.
"I want to play with these girls for as long as possible. I want to play at a European finals with them. So we want to stick together and get there as a team," she says.
