Kolo Toure believes Alexander Hleb was lucky to escape serious injury after being fouled by Paul McShane in Arsenal's 3-2 victory over Sunderland.
McShane was shown a straight red card by referee Rob Styles after a challenge on Hleb in the final minute of Sunday's Premier League clash.
Hleb, who had been strechered off against West Ham a week earlier, was hurt by McShane's tackle but there did not appear to be any lasting injury.
Toure, standing in as skipper for William Gallas, was not happy with the Sunderland player.
"When I saw that on the replay, I thought the intention was bad," said the Ivory Coast defender.
"He did not get to Hleb and I think sometimes it is better to relax (when a player is coming towards you).
"It can make something worse happen. The referee did well to send him off.
"I spoke to Alex afterwards and I said 'they want to kill you' - but I was just joking.
"Alex is such a great player. He is okay, all right."
Arsenal are top of the Premier League and unbeaten this season, but Toure feels it would be premature to think about winning the title.
"For the minute, we don't talk about it," he said.
"We just focus on what we are doing well, enjoy it and make our fans happy. At the end we will see how far we go.
"It is really important for the team to keep on winning because the confidence is going higher and higher."
Wenger bemoans international break
Arsenal do not play again for another fortnight but Arsene Wenger does not expect many of his players to have much rest as they jet off to play for their countries.
The Arsenal boss said: "I would prefer a complete break, and not an international break for the players.
"They will come back after playing two games with a lot of pressure on because many countries now play decisive games.
"Then when you come back, you play straight away in the championship and the Champions League again. It is too much."
