PFA chief executive Gordon Taylor believes it is time for the FA to intervene after Luis Suarez and Patrice Evra failed to shake hands before Manchester United's clash with Liverpool. The pair were meeting on the pitch for the first time since Suarez completed an eight-match suspension for racially abusing the Manchester United defender. Evra appeared to offer his hand to the Uruguay striker but he bypassed the Frenchman and went straight to David de Gea. That set the tone for a fractious encounter at Old Trafford in which the police were twice called on to intervene in incidents in the tunnel and dressing rooms and Evra sparked more controversy by wildly celebrating United's win in front of Evra at the final whistle. Taylor said: "What Suarez did was disrespectful, inappropriate and embarrassing. I just felt quite sick in my stomach. "If anything, Patrice Evra was the victim and he was prepared to put his hand out. "These players are expected to be role models but if we have a situation where nobody accepts the findings of hearings and just carries on regardless, all you get is anarchy. "Now the Football Association have to step in because the whole situation has gone too far. "Suarez had a chance to put everything to be yesterday, in front of a worldwide audience. "The fact that he chose not to is, quite frankly, depressing."
