JOHN O'Shea, captain for the night, couldn't believe how easy Ireland made it for Germany.
Of all the possible outcomes, O'Shea never imagined he would skipper an Irish team to the worst competitive defeat in our history.
He said: "Obviously it's a massive humiliation.
"There is not much you can say. Germany are a very good team but we gave them a helping hand with lots of the goals. We started the game not too bad and kept them out quite comfortably. But then they got the first two goals.
"We obviously changed it a little bit to have a go in the second half and left ourselves a little open and they took full advantage to it," said O'Shea.
Alluding to the ineffectiveness of the Irish at pressing and closing down the Germans, O'Shea said: "If you have to lose, there's a way to lose, and this certainly wasn't the way."
Jonathan Walters, who played on his own up front for most of the match, agreed with O'Shea that more was needed from within the team, even though Germany were the better side.
"They had plenty of the ball. In games like that, when you've got players doing what they want in midfield, it's got to be a case where you put a challenge in at some point, somewhere to get everyone going," he said.
"Maybe we missed that (aspect) a little bit. We've got to go again on Tuesday now so our mind is on that straight away.
"We have to bounce back, there's no other way. We'll probably speak about it tomorrow between ourselves and then get on with it.
"I've never been in a game like that before where it's been like that, never, and hopefully I never will be again."
Seamus Coleman, who had a torrid time at right-back and was partly to blame for the first two German goals, admitted: "It's going to be tough to sleep after that.
"We just found it so hard to get near them. They're top-class players, but that's no excuse.
"They're probably the best team I've ever played against but we have to forget about it and put it behind us as soon as possible," added Coleman.
Meanwhile, Irish goalscorer Andy Keogh doesn't want to hear of the manager being under pressure, despite the team conceding six goals.
Keogh came on as a 69th-minute substitute and headed the home team's goal in injury-time as the Germans romped to a 6-1 win.
"I don't think anyone has turned against him (Trapattoni)," said Keogh. "His record speaks for itself. We should have qualified for the World Cup (beaten in a play-off) and we did qualify for the Euros. I don't think there's any problem there.
"We're all very disappointed. We got beaten by a better team all round. The lads are gutted. We just have to make sure we do the business on Tuesday.
"Germany are favourites to win the group. They'll take points off the other teams, being realistic, and we have to hope for that."
