Northern Ireland manager Michael O'Neill was disappointed his side could only manage a 1-1 draw against Luxembourg in their World Cup 2014 qualifier in Belfast.
The Green and White Army were looking to bounce back from a 2-0 defeat away to Russia in their opening qualifier, and made the perfect start when Dean Shield gave them a 14th-minute lead.
Northern Ireland continued to dominate proceedings for the remainder of the game, only to see Daniel De Mota snatch an equaliser four minutes from time thanks to a fortunate deflection off Ryan McGivern.
And O'Neill lamented his side's missed opportunities, believing his players let their performance deteriorate in the second period.
He told Sky Sports: "I am very disappointed, we had enough chances to win.
"In the second half we let our standards drop. Our energy levels dropped too."
The 43-year-old also aired his displeasure at the standard of refereeing on display at Windsor Park.
Aside from Ireland’s three disallowed goals, O’Neill rued the stunted flow of the game due the continual supposed fouls.
"The game was disrupted by offside calls," he added.
"There were too many free kicks and too many disruptions."
