Denmark then silenced the home fans three minutes later when Christian Eriksen clinically turned home Jorgensen's cross to put the visitors ahead. Then we conceded two goals quickly after that and then it's an uphill struggle.
With the tie perfectly poised after a first-leg goalless draw in Denmark, the Irish got off to a superb start when Shane Duffy headed home on six minutes after a Robbie Brady free-kick.
Denmark's Christian Eriksen celebrates after scoring his side's fourth goal during the World Cup qualifying play off second leg soccer match between Ireland and Denmark at the Aviva Stadium in Dublin, Ireland, Tuesday, Nov. 14, 2017.
"We were well beaten in the end, no question about that".
Ireland were well beaten at home to Denmark on Tuesday night, going down 5-1 to leave their World Cup hopes lying in tatters.
"The goals were so sloppy", Ireland manager Martin O'Neill told Irish national broadcaster RTE.
"I am really disappointed", said O'Neill. We needed either of those to go in to get a real foothold in the game.
"We'll take this with us and try to score as many goals as possible at the World Cup as well", said the midfielder, who doused former worldwide defender Lars Jacobsen, who was broadcasting for Danish TV, with champagne as he celebrated.
"Clueless. Absolutely clueless. To allow the players like they have the space, the time, in the key areas of the pitch, even the substitutions, Ciaran Clark coming off - unless he's injured - with Ward going to centre-half, I really don't know what I've witnessed".
"It is an incredible feeling", said Eriksen.
"'Thank you very much for giving us space', because they locked us down in the first leg very well and Eriksen was out of the game, and today he was fantastic."
"Denmark were stronger, they were better than us on the evening and well done to them".
Sub Shane Long threatened to get one back for the Boys in Green but there was still time for none other than Nicolas Bendtner to rub salt into the gaping Irish wound, converting a spot-kick after the ex-Arsenal man had been felled in the box by McClean. The second goal was the most technical one, better than the others. I take the more clinical shot rather than passing.
