Republic of Ireland boss Martin O'Neill rued a "comedy of mistakes" after his side were thrashed 5-1 by Denmark in their World Cup qualifying play-off.
A suffocating goalless draw in Copenhagen was followed by a rollicking affair in Dublin, one which the Irish started superbly, taking a sixth-minute lead through Shane Duffy.
But Age Hareide's men stuck to their task and a Cyrus Christie own goal was followed by Christian Eriksen's superb hat-trick before Nicklas Bendtner's penalty capped a brutal Danish demolition job.
However, having seen Daryl Murphy and James McClean narrowly miss half-chances with Ireland still ahead, O'Neill lamented his side's inability to keep the pressure on.
