Jim Magilton sees red over loss
Jim Magilton pointed to Dale Gorman's sending off as the pivotal moment as Northern Ireland suffered a defeat to Scotland in their opening European Under-21 Championship qualifier.
The score was tied at 1-1 when Stevenage midfielder Gorman received his second yellow card of the game in the 59th minute.
Two minutes later Ryan Fraser cut in from the left to fire Scotland in front and they held on to defeat the 10 men.
Northern Ireland had made a great start to the game, going 1-0 up after just seven minutes.
A long ball out of defence found Michael Duffy on the left wing and his first-time cross was tucked in at the back post by Charlton Athletic's Mikhail Kennedy, who recently scored on his first-team debut.
Ryan Christie, who recently signed for Celtic, struck the equaliser on 33 minutes after the Northern Ireland defence failed to deal with a long ball down the middle.
The Scots then pounced almost immediately to win the game after Gorman's dismissal.
"We played well and there was nothing in the game for an hour, but we had to reorganise after Dale was sent off and Scotland took advantage of that to score while we were still adapting," said boss Magilton.
