Switzerland scraped into next year's World Cup, their fourth finals in a row, after being held to a goalless draw at home by a valiant and workmanlike Northern Ireland who came desperately close to forcing extra-time on Sunday.
The Swiss qualified 1-0 on aggregate, the tie ultimately being decided by the hugely controversial penalty converted by Ricardo Rodriguez in the first leg in Belfast on Thursday.
They were again indebted to Rodriguez on Sunday when he cleared a goalbound header from Jonny Evans off the line in stoppage time as Northern Ireland pressed for an equaliser.
The Swiss, boasting a much more illustrious and talented line-up, could have done it in style as they dominated the first hour but squandered a hatful of chances.
Instead, on a slippery pitch which cut up badly, they relinquished control for the final half hour and were forced onto the back foot, fraying the nerves of the home crowd.
Forward Haris Seferovic was the biggest culprit and was jeered off by the home crowd when he was substituted by Breel Embolo.
After failing to muster a shot on target in the first leg, Northern Ireland forced Swiss goalkeeper Yann Sommer into action after only three minutes when he tipped over a 25-metre shot by Chris Brunt over the bar.
Seferovic glanced a free header wide from Xherdan Shaqiri's cross and shot wide of the near post when he was released by Steven Zuber as the Swiss began to take control.
Numerous other chances went begging and the Swiss lost their swagger as the game wore on.
They survived one fright when Conor Washington headed wide from James Ward's cross at the end of a quick break while another break down the left by Washington ended with George Saville shooting weakly at Sommer.
Seferovic should have settled it in the 85th minute but instead shot high and wide -- and was substituted almost immediately.
