We don't wish to tempt fate, but history is on the Republic of Ireland's side.
Martin O'Neill's side take on Bosnia-Herzegovina this evening at the Aviva Stadium, with the small matter of a place at Euro 2016 to be decided.
Ireland hold the advantage after last Friday's 1-1 draw, thanks to Robbie Brady's away goal, and history suggests they'll prevail tonight.
Newstalk have looked back at the history of play-offs for World Cups and European Championships and found, when the first-leg ended in a 1-1 draw, the home side in the second leg usually advance.
Of the five play-off games which have ended 1-1 since the ties were introduced to qualifying, the team who played at home in the second leg have advanced on four occasions.
Ireland have twice been on the wrong end of this statistic.

Back in 1997, Ireland and Belgium played out a 1-1 draw at Lansdowne Road in the fist leg, but lost the away tie 2-1, and missed out on the World Cup in France.
Two years later, Turkey escaped from Dublin with a 1-1 draw, and a bad tempered return leg finished goalless, meaning Ireland missed out at a place at Euro 2000 due to away goals.
Let's hope history is on Ireland's side tonight though.
