Everton manager David Moyes was furious that he was sent off in the closing stages of Wednesday's fine 2-0 victory at Manchester City after becoming involved in a fracas with Roberto Mancini in the closing stages of the match.
Mancini confronted Moyes, who had caught the ball before making a substitution, seemingly believing that the Scot was time-wasting.
When the spat was finally diffused, both managers were sent to the stands, but Moyes was adamant that he was the innocent party.
He said: "Next time I might just let the ball run through. I caught it because I was making a substitution, I would have thought it would actually have helped him.
"I was very surprised, I didn't know what I'd done wrong. Maybe I held onto the ball a second or two longer than I should have done but I was trying to make a substitution. But if I'd let the ball go, let it run down the touchline - I actually speeded it up.
"I wasn't the one waving my hand for bookings. I shouldn't have been sent off, simple as. However, he was showing his passion for his team and his club and I can accept that."
