Furious Bolton Wanderers boss Owen Coyle claimed Arsenal's William Gallas should have been sent off for a challenge which left Mark Davies with a suspected serious ankle injury during his side's 4-2 defeat at the Emirates Stadium.
Coyle was angry with both Gallas' challenge and Arsenal's decision to play on which saw them equalise through Cesc Fabregas before going on to win the game.
Referee Alan Wiley failed to give a foul on Davies when Gallas appeared to miss the ball and followed through clumsily on the Bolton midfielder's ankle.
"I think it was closer to an assault than a tackle," fumed Coyle. "I would suggest it's probably closer to a sending-off as far as I'm concerned.
"The lad is prostrate on the ground and Arsenal, being full of fair play as we keep hearing, have carried on and scored an equaliser. That is hard to take.
"It was a bad tackle, there is no getting away from it.
"You can accept it if he gets a bit of the ball, because that is the game we play and it can happen, but he has not touched any of the ball and it rubs salt into the wounds.
"I don't want to sit here and make excuses, but I have seen red cards for less."
