Liverpool midfielder Javier Mascherano could face a charge of violent conduct by the English FA, following an off-the-ball elbow in Tuesday's cup win over Leeds United. The Argentine caught Leeds' Jermaine Beckford in the back of the head, but Liverpool boss Rafa Benitez sees nothing wrong in the challenge. "I think it is just nothing," said the Spaniard after the game which his side won 1-0. But Leeds manager Simon Grayson has another opinion. "Mascherano's turned and put his arm up; it went a bit too high. I've looked at replays. I'm not saying it's malicious and I'm not saying it's not, you can't really tell," he said. "Some players have been sent off for that, some haven't, sometimes these things go your way, sometimes they don't."
