Gillian Pinder is backing Ireland to get the job done in Wednesday's Pool A EuroHockey Nations Championship clash with Spain on Wednesday.
The Green Army got their their campaign back on track this afternoon with a 1-0 victory over Scotland.
It leaves them facing the Spanish - who were more comprehensive 4-1 winners over the Scots the first day before losing 7-1 to the Netherlands this evening - on Wednesday morning.
Victory there would see Ireland reach the European semi-finals for the first time, as well as securing qualification for next year's World Cup.
The countries played a five-game series in January, with Ireland winning two and drawing two of those meetings.
And Pinder told RTÉ's Game On that she's hopeful those wins will stand to the Irish this time around.
"I would expect Ireland and Spain to be a relatively even contest," she said.
"Spain are ranked seventh in the world and we're one place behind them. Each team will have a handful of chances and whichever team defends the circle better and takes the opportunities that they do create for themselves will come out victorious in this game.
"Both teams will know each other really well and it's those fine details of who executes the game plan better on the day that will come out on top."
Naomi Carroll got the only goal but the Irish might have had a couple more with Anna O'Flanagan and Nikki Evans going close.
For Pinder, the fact that they created so many chances is a positive heading into the decisive fixture.
"It would be a lot more worrying if you were heading into the Spanish game having not created those opportunities," she pointed out.
"While they're disappointed, the forwards in particular will have a good look and see what they can do better - be that mindset, bringing more aggression, or shot selection. If they can take those opportunities, put some goals on the scoreboard, they're going to be a difficult team to roll over.
"If they don't then this tournament is going to flip on its head and be a very difficult one towards the end.
"The stakes are higher this summer than they've ever been before but I think the players thrive under that pressure. We've seen Irish teams grow into tournaments and just thrive off that momentum."
Pushed for a prediction, Pinder said: "I think it's going to be 2-1 to Ireland and it's going to be a nail-biter."
