Shay Plays His Part In Cardiff!
The Wigan midfielder headed Wales ahead in the first half, but slowly the Irish forced their way back into the lead with goals from Robbie Keane and Kevin Doyle.
And as the second period moved to a close, the visitors were on the brink of their first win in Group D since March, a run that has cost them qualification and Steve Staunton his job as manager.
Wales, though, had different targets. They needed a much better performance than some woeful recent efforts, and this time boss John Toshack got what he wanted.
It fell to Koumas to step up and crash home the late equaliser from the penalty spot, to give Wales some comfort from a disappointing campaign.
