First of all I think Mascherano was disappointed with his booking," he told the Sky Sports show. "We could tell the minute it happened when he slid in on (Paul) Scholes, a lot of referees would have let it go, but Steve Bennett decided that he would book him.
"He was rattled by that, Mascherano, you could see it in his play.
"Steve Bennett has his own way of refereeing a game but it is not mine. A lot of people might say that he was absolutely, 100 per cent right. I don't think he was.
"I agree that he (Mascherano) should have stayed away. He didn't, so forget that. Are you telling me that Steve Bennett is going to send off every single player that comes up to him and says, 'what's happening?'."
Gray argued that there was a big difference between Cole's and Mascherano's misdemeanours and that Cole, who escaped dismissal, should have seen red while it was rough justice on Mascherano.
He said: "Ashley Cole should have been dismissed in mid-week. No doubt about it.
"His treatment of the referee was a disgrace. To turn his back on him like that and treat him with such contempt, whether you like referees or not, was wrong, ill-advised and he shouldn't have done it. He should have been sent off and that might have been the end of it.
"But if you are telling me that if you go up to a referee and you stand in front of him and you are being not aggressive and he didn't swear at him (you should be sent off).
"Where are we going with this game? Where are we going with it? Do me a favour. There are problems in the game, we know there are, and Ashley Cole's was an unpleasent part of modern day football.
"But if we are going to send players off for going up to a referee and saying, 'what's happening?', and the referee cannot handle it and reacts like that every time, then we have got a problem.
"I will tell you something that happened in the game: Another player, in the second-half, went over to Steve Bennett and he gave him a verbal volley of industrial language. Right at him.
"I'm not telling you (who) because it is not my business to get players into trouble but that is what happens. Suddenly, if you say 'what's happening?' to the referee, you get sent off, but if you give him a volley, you don't."
