The ECA wants Fifa to scrap August international friendlies.
“We will intervene more and more in the international match calendar,” Rummenigge said.
“Some countries are already playing their third series of internationals since the World Cup. We need deep discussions to find a solution.
“Federations like Fifa need to recognise that the players are our employees and we have to be involved in these kind of discussions.
“The August friendly date was a nonsense. We have to make Fifa understand that certain things don’t make sense.
“We have to discuss this with Mr (Sepp) Blatter and his colleagues in order to do something for the good of football.”
He added: “It is very dangerous to come back from a long tournament with only three weeks of holidays and then play a friendly for the national team. That is the kind of date that has to be given up.”
