Referee Manuel Grafe correctly ignored his lineman's flag for offside allowing Estonia to score a late winner in the 2-1 defeat of Northern Ireland at Windsor Park. Northern Ireland coach Nigel Worthington told Sky Sports 4: "All I saw was the linesman's flag go up, I turned around to get a bottle of water and all of a sudden the ball's in the net.
"I saw the flag, the players saw the flag and stopped and the ball's carried on.
"Some things you are in control of, some you aren't. It's harsh, but it's been done - he's showed his hand all night, but we'll stick together and get on with it."
The result, coupled with Serbia's draw against Italy, ended Northern Ireland's slim mathematical hopes of qualifying for Euro 2012 from Group C.
"I thought in the first half we played exceptionally well, and they played particularly well in the second," he said. "It's hugely disappointing but we'll have to bounce back.
"I can't fault the players for their commitment and attitude. I don't think there's a hell of a lot else we could have done, we've had solid performances, good commitment, pride in the shirt, and that's all you can ask.
"That's just frustration and disappointment, it seems to be the fashion nowadays. I know where we're at with the size of the country and the quality of people we've got, and we'll try our best to turn it around."
