Andorra 0 Rep of Ireland 2:Kevin Doyle's 10th senior international goal set the Republic Ireland on the road to a 2-0 victory in Andorra as Giovanni Trapattoni's men stayed on track for second spot in Euro 2012 Qualifying Group B.
Doyle's seventh-minute strike gave Ireland an advantage they never threatened to surrender and when defender Ildefons Lima deflected Aiden McGeady's shot into his own net 13 minutes later, the points were effectively safe.
Russia's victory in Slovakia means they will win Group B if they beat the Andorrans at home on Tuesday evening, but a draw with Armenia will be enough to send the Republic into the Euro 2012 play-offs.
"I think we started very well, with determination and a will to win," said Giovanni Trapattoni afterwards. "And in this 30 minutes the team showed us that the result was granted.
"Robbie Keane could also have scored immediately, we had two or three chances in the first 10 minutes and we could have had a three-goal advantage."
Looking ahead to the visit of Armenia, the manager added: "Obviously with this result we have to play to win, though a draw would do, but with this mentality we can win."
