Manchester United boss Sir Alex Ferguson concedes Gary Neville should have been sent off in victory at West Bromwich Albion.
The Baggies were seething at referee Chris Foy's failure to punish Neville's first-half lunge on Graham Dorrans with a penalty and a red card.
Neville certainly did not touch the ball as the Scot, with only Tomasz Kuszczak left to beat, tumbled to the ground.
And even Ferguson accepted the ref got it wrong.
"Gary was lucky to stay on," said the Scot.
"It was a penalty. At first I thought he had got a touch but when I saw it again, he was lucky."
As it turned out, West Brom got a penalty anyway after Rio Ferdinand had tripped Jerome Thomas in the second-half.
Unfortunately for the hosts, Peter Odemwingie dragged it wide, which proved the catalyst for a late rally that secured United their win.
"If you miss a penalty playing at home, midway through the second half, it is a bad blow," said Ferguson.
"If they had scored, they would probably have won the game because they had the momentum. They would have got impetus from the crowd as well and we weren't playing as well as we can."
Baggies boss Roberto di Matteo added: "It was very clear from everyone's view.
"Only the main man who was supposed to see it didn't.
"I spoke with the fourth official during the game but he can't do anything about it and nothing is going to change now.
"I don't know if there is anything in the referee's mind. But it was so clear. Neville didn't touch the ball and my player is through.
"I would have liked to see what we would have been like against 10 men. It wouldn't have meant we would have won but you never know."
