"It is clear. We must be in agreement but the question is how to do it? It is not easy," said the Liverpool boss. "If you have a solution maybe we can see but the solution is very difficult to find," he said.
"The managers have to tell all their players not to dive and play football but sometimes you cannot control it.
"And sometimes it is very difficult to decide who is diving and who is not.
"Sometimes it is very clear and then you can say something but if it is not clear you have to be careful and have to analyse.
"In some cases video evidence would be useful. But you can see things from four or five different angles and three people can say different things.
"I am in agreement it is necessary to do something but the first thing is to say to the players 'Don't dive' and after, if you have clear evidence, maybe you could do something."
