Player ratings: Seamus Coleman and Adam Idah to the fore
Some of the enthusiasm that greeted Ireland's encouraging draw with Belgium curdled as the Swiss inflicted a 1-0 defeat on the hosts on Tuesday.
Here are the player ratings after what may be John O'Shea's final game as Ireland manager - for the time being.
Gavin Bazunu 5
An evening which hardly helped his cause in the tussle for the No. 1 jersey. Positioning was naturally questioned after being beaten by Xherdan Shaqiri's low free-kick to his right hand side. Would certainly have been culpable had Granit Xhaka's shot from distance crept inside the post following a poor clearance.
Perhaps spooked by Caoimhin Kelleher being handled the jersey for Saturday's game? Probably has been leap-frogged in the pecking order, though who knows what view the incoming manager will take (he could be the same as the interim manager).
Seamus Coleman 7
Had relatively little joy in attack in the first half, where he kept being caught offside when trying to exploit the Swiss high defensive line.
Was a confident and reassuring presence when asked to shift into the back three after Matt Doherty's introduction for Omobamidele.
Frustrating moment at the end, when he danced elegantly past a dangerous Swiss press but then sprayed a crossfield ball over the head of Ferguson.
Was booked for what was - in old money - a pretty flawless slide tackle in the final five minutes.
Unfortunately, the linesman standing near was impressed by the power of the Swiss player's injured yelp.
Andrew Omobamidele 6
Looked a threat on set-pieces, even if he and Ferguson had the misfortune to head the same ball at one point.
Was outmuscled in a battle for possession after being caught in the wrong position for a Swiss ball over the top. Led to a dangerous situation.
