Steven Davis choked back his misery of being part of a “completely unacceptable” Northern Ireland side, in a game which saw Luxembourg run out as 3-2 victors.
The midfielder said manager Michael O’Neill was fuming at both the interval and after the final whistle, before confessing it was too difficult to talk about the performance.
He said: “Michael was furious, and that’s understandable. Some words were said and they are to stay in the dressing room.
“Honestly, I am finding it really hard to talk about it this soon after the game. I am just so frustrated.”
Davis added his role as international captain was a footnote and that he is just as culpable as any individual. “Is it any different for me as captain? No, I think just generally as a player I wasn’t at it. I was about half a yard off.
“I don’t think there were any positives, it was a totally unacceptable performance. We let down Michael and the staff, and the fans who came out and gave us such good backing.
“It’s strange how you go from such a mature performance against Russia and you come in today and it looks as if we had never played with each other before,” he added.
“It’s hard to put your finger on it but just seems as if we didn’t get the second ball, pass it well enough, guilty of everything really.
“I don’t think we underestimated Luxembourg, we know ourselves if we want results we have to be on it every single game and this time we weren’t on it.”
