Dara O'Shea and his Republic of Ireland team-mates will head into the European Under-21 Championships qualifier in Armenia still smarting from the one which got away against Italy.
Ireland are seeded fourth in Group 1, but currently lead it after a fine start to the campaign which brought victories over Luxembourg, Armenia and Sweden.
However, a 0-0 home draw with the fancied Italians last month was followed by a 1-0 defeat in Iceland.
And O'Shea and his team-mates are determined to put that right in Yerevan on Thursday afternoon before they host the Swedes at Tallaght Stadium on Tuesday evening.
West Brom defender O'Shea said: "We were actually very disappointed with the Italy result because we knew that it was ours for us to win, really.
"Going out to Iceland and losing there was a huge blow for us and something that we're really looking to rectify in these two games.
"But it just shows how much confidence we have and that we back ourselves, and that we know we should be winning every game and that we can win every game."

Stephen Kenny's side have threatened to upset the apple cart from the off and although they have played a game more than Iceland and two more than both Italy and Sweden, they remain confident that they can spring a surprise.
O'Shea said: "From the start, the gaffer has said to fear no-one. We can't go out fearing anyone, we need to go out and have the mentality that we are going to win.
"But I don't think being fourth seeds affects us at all. It almost gave us a bit of motivation, the fact that we were fourth seeds, but we knew that we were well capable of winning the group."
Victory in Armenia seems a must if they are to achieve that dream, but O'Shea, who has been ever-present in the campaign to date, knows that will be tough, particularly with the likes of Troy Parrott and Aaron Connolly now among the senior ranks, Jayson Molumby and Lee O'Connor suspended and goalkeeper Caoimhin Kelleher ruled out.
He said: "It's a huge blow because we're missing players who have played a key part in the campaign so far, but I think it just shows the depth in our squad, the players that we've brought in."
