Leicester conceded two late goals at Nottingham Forest in a 2-2 draw and had keeper Kasper Schmeichel dismissed for two yellow cards.
Foxes boss Sven-Goran Eriksson refused to defend Schmeichel after his sending off proved crucial in the east midlands derby.
The Dane tweeted after the game: "Didn't know I had been booked as I had to my back to the ref otherwise I would never have done that", but Eriksson was unsympathetic.
"I am not going to try and make excuses," said the Swede.
"Kasper said he didn't see the first yellow card and he might be right but the penalty and the sending off changed everything.
"We were much the better team for well over an hour and although we are disappointed not to have won the game, I think we showed today that we are a good team.
"We looked a good side, were very solid and played some excellent football. But the penalty was crucial and we thought it was very soft.
"A week ago against Reading we were very poor but today's performance showed me that we are getting there. Let's hope we can get the silly things out of the way early in the season."
Forest boss Steve McClaren admitted: "Fortune favoured the brave today and that's twice we have shown our character this season, having come back in the Carling Cup against Notts County.
"We are a work in progress and there is a lot to do but we have salvaged something which looked impossible at half-time. The good thing for us was that we were only two goals behind because three would have put us out of it.
"We would like to forget the first half but things improved in the second and we built some momentum that led to the penalty.
"When you are building a new team, as we are, inconsistency is a problem but the fighting qualities we showed will be the foundation on which we build. We have to maintain that and improve the quality."
