FIFA president Sepp Blatter has again urged players not to leave the pitch in protest at racial abuse from fans.
In an interview with Sky Sports News, Blatter praised Kevin-Prince Boateng for leading AC Milan off after being abused during a friendly last week - but he maintains this is not a long-term solution to ending discrimination.
"You remember the Boateng problem, with him running away," said Blatter. "I made a comment on that and I still have the same feeling.
"It is good what he has done, it is good to have this impact - to say look what has happened - but it cannot be a solution.
"You can never solve any problem in your private life or your economic life by running away.
"Listen, it was a warning, if you don't take care of our sport we will do it. It was a warning but it can't be the solution
"We will make a summit with all the players concerning racism and discrimination. Then there must be a lot of solidarity and understanding. We have to eradicate it.
"It can only be done if all the players are participating, and the players are also the spectators."
