Martin O'Neill admits he may appeal Zat Knight's controversial red card against Chelsea.
The Aston Villa boss was left incredulous on the touchline when late in the first half his player was dismissed by referee Phil Dowd, for what he perceived to be a professional foul on Michael Ballack.
A 4-4 draw that had two penalties and three red cards was not short on controversy and with regards Knight, O'Neill is adamant Dowd got it wrong.
And with this in mind he is weighing up whether to lodge an official appeal.
He said: "Zat Knight's sending off was a major moment.
"I've seen it a couple of times now and while I'm aware that I have the benefit of replays I will look at it again.
"I might appeal and we have until noon tomorrow to do so. It wasn't a penalty.
"The Chelsea player went over and there was no contact. That's my view - it wasn't a penalty.
"The free-kick they got with three minutes to go was not a free-kick. It didn't look like it could be possible.
"I've seen it again since but how did I feel at the time that he might just give it? He did.
"The referee was in a position to get that one right because he was on the spot."
