Fasten your seat belts and prepare for the continuation of the World Cup roller-coaster.
Already Irish fans are predicting that the Republic will thrash Spain, their most likely opposition for the next game, and even go all the way to the finals. Nothing, it seems, is impossible.
The full-time whistle was hardly blown in Yokohama yesterday before Dublin fans were dashing from pubs into the almost deserted streets with their mobiles to place bets on Ireland taking home the cup.
Martin Lynch from Mullingar, who has travelled around the world to support the Irish soccer team, but watched yesterday's game in Dublin's All Sports Cafe, said: "This World Cup is so open now that Ireland could go the whole way to the final. I fancy them against any of the teams remaining.
"I've been all over the world with the Irish team, but this is the best day ever," he said.
Templeogue man Johnny Ennis said the Spanish would be afraid of the Irish. "We will beat them 1-0 in extra time. It'll be a Brazil-Ireland final. Remember where you heard it first," he said.
Alan McCabe from Dundalk and his friends also travelled to Dublin to see the game in a Temple Bar pub and donned Saudi headgear for the occasion.
"The atmosphere is brilliant," he said. "Everybody was writing us off at the start because of Roy Keane. They turned around and put up a great performance and who knows after this what will happen. Spain are a good side, but there is nobody we can't beat on a day we put in a gutsy performance.
"If we win on Sunday we're going to blow the bank and go to the quarter-finals," he said.
It seems they're not the only ones. Travel agents have reported huge interest in hastily organised package deals to Korea which are selling from €2,350.
Even the dogs in the street were celebrating yesterday. Brandy, a half-labrador, and Shadow, a Siberian husky, were dressed in Irish jerseys and paraded through the capital by their owner, Paul Moran, originally from Westport and now living in Drumcondra.
He explained that he could only get white jerseys for them. "Large boys' to medium-sized green home jerseys can't be got for love nor money," Paul said.
Last night Paddy Power Bookmakers was offering odds of 9 to 4 that Ireland will win their next match and reach the quarter-finals. The odds on the team reaching the semi-finals are 8:1; reaching the final 18:1; and winning the World Cup 50:1.
