Fifa vice-president Jim Boyce says Luis Suarez diving antics are spreading a cancer with the game It can be dealt with retrospectively by disciplinary committees, and it is done so in some associations, and I believe that is the correct thing to do. It can at times be very, very difficult for referees to judge whether something is a foul or a fair tackle and if players are diving then it makes their job even harder. The issue has been discussed by the FA and the leagues before without any change in policy. The Premier League have previously suggested a three-man panel to review contentious incidents after every weekend, which could include simulation, and would be open to renewing discussions on bringing in such a system. The FA said the issue was often reviewed. A spokesman added: "Simulation is not something that the FA currently take retrospective action over but it is an issue that is often reviewed and discussed by the game's stakeholders." But Liverpool boss Brendan Rodgers leapt to the defence of Suarez, saying: "At this moment there seems to be one set of rules for Luis and another set for everyone else.
