Clarence Seedorf has said AC Milan players were wrong to abandon their friendly with Pro Patria after some were racially abused.
Kevin-Prince Boateng stopped during play to boot a ball at the section of the crowd who were airing racial chants before the referee suspended the match.
Former Milan midfielder Seedorf said: "I don't see it as such a positive thing because [it] empowers more and more of this behaviour."
While the majority of players have voiced their support for Milan and Boateng, Seedorf said those guilty should have been thrown out of the stadium.
"They should just be identified and kicked out of the stadium," he said. "Leave the 90% that were enjoying the match and finish the game."
"If Boateng was able to identify the whole corner, you just kick the whole corner out, That is how I think it should be handled," Seedorf told BBC Sport.
"Walking away? Yes, you send a signal. But this has happened more than once and I don't think it really changes all that much. We are just empowering that little group with their behaviour to make this mess."
