Republic of Ireland earned a 1-0 win over Switzerland in their international friendly at the Aviva Stadium in Dublin on Friday evening.
Ciaran Clark scored the winner with a header inside the first three minutes of the match, and despite the Swiss having the majority of possession, they were unable to break down Ireland's defence.
The victory is the first that the nation have sealed over Switzerland since 1992.

"You have to take into consideration in the next six or seven weeks, that some of the major players who have been great might fall foul of injury, so players here should take this opportunity, late and all as it may be, to feel as if they have got a chance," the Irish Examiner quotes O'Neill as saying.
"Listen, let's be fair about it, the players who are coming in late here have a bit to do, I must admit, to go and cement something. Everything would probably have to go pretty well for them individually.
"But it's not impossible and it's happened before, and that's why I'd like to open the door for them, to feel as if they have got a chance. And, for instance, one or two of them - let's say they didn't make it - they know they are right maybe for the World Cup campaign coming up almost immediately."

When asked for his thoughts, O'Neill joked: "It depends on how good-looking the girls are. If they're really attractive, they're very, very welcome. The uglier ones, I'm afraid not."
