Euro 2012: Giovanni Trapattoni urges Ireland to keep believing after morale-sapping defeat to Croatia It's important we recover psychologically and believe again because we have to remember how many games we had played without conceding a goal. The Republic of Ireland were undone by impressive Croatia striker Mario Mandzukic within three minutes, and although defender Sean St Ledger dragged them back into the game with a 19th-minute equaliser, they fell behind once again two minutes before the break. Everton striker Nikica Jelavic made the most of Stephen Ward's miskick and a tight offside decision to make it 2-1 and, when Mandzukic's 48th-minute header came back off the woodwork and went in off keeper Shay Given, the die was cast. Trapattoni said: "In the first half, they deserved to win because they were superior in midfield. We played better in the second half. Croatia boss Slaven Bilic was delighted, but not surprised, by his side's powerful display, which sends them into their clash with Italy brimming with confidence. Bilic said: "I was expecting this kind of result. We were preparing for this victory. We knew everything about this Irish team. We knew we were the better team, but you never know before the match. I can just congratulate players from both teams. The match was very good. I'm completely satisfied with the way we played. We were really strong in midfield. I respect the Irish team. The Irish team didn't lose for the last 14 matches, they were in a group with Russia, they drew 0-0 in Moscow - this means they are a strong team. We played very well and we beat a strong team. From the first minute of the match, I was really sure, really confident. We were the better team on the pitch and it would have been really hard not to win this match. We were dreaming about this position. Probably, one victory will be enough to go to the quarter-finals.
