Simply put, tonight's clash between Wales and Ireland could be the biggest game in Irish football since being defeated by the hand of Thierry Henry in 2009.
Ireland sat second in group D, level on points with group leaders Serbia at the end of 2016, but a drastic dip in form has seen Ireland slip to third, only securing two victories in 2017.
So now we have to win. And win we may. We've an ok against record over the years.
Today, we're testing your knowledge of that record. We want you to guess every Irish player to score against Wales since 1990.
In that time, we've played each other on 10 occasions, with five victories for the Irish, one victory for the Welsh and four draws.
A genuine die hard Republic of Ireland fan should remember most of these, but there are some very obscure ones out there. We've given you a generous eight minutes, and a respectable score should be in the region of 8 out of 12.
