The Football Association is reviewing the footage of Chelsea midfielder Eden Hazard's red card for kicking a ballboy at Swansea.There has been criticism of Foy for his dismissal of Hazard, but former Premier League official Dermot Gallagher praised his handling of a difficult situation. He said: "The referee has taken the correct action, It's against the laws of the game to commit violent conduct on anyone under the jurisdiction of the game. "I can't reinforce how switched on the officials were. It would have been so easy for the assistant referee not to pick that (incident) up - but he did." Gallagher continued: "There's no defence for that. Someone said it was borne out of frustration but you have to accept it. I don't want to see it again. "It was an extreme but you can't have that at a football match. It's been addressed - and the action which has been taken is strong and correct." Steven Martens, the chief executive of the Belgian FA (KBVB) has warned that Hazard must learn to control himself: "It's unfortunate and of course it's not something we are proud of. No football authority or person interested in football likes to see acts of violence or lack of respect and this is what happened. "It might have happened in the heat of the fire but professionals are expected to be able to control themselves. They have to be able to control their emotions and when they don't that's unpleasant in general. "Of course as we are the Belgium FA we don't like it to be a Belgium national squad player but I am very much convinced that Eden himself will realise that. "Eden is more than intelligent enough to understand that this is going to be a lesson learned for him. All of us make mistakes in life."
