Before the game the two teams lined up behind a banner bearing the slogan "All united against racism in football", but
large sections of the 50,000 crowd at the Bernabeu responded with racist chants and monkey noises directed at England's black
players during Wednesday's match.
"I think we should try and put ourselves in the player's position," said Eriksson.
"Things like this should not happen and it certainly doesn't help the players. There must be some sort of protest."
England captain David Beckham said he was deeply disappointed by the behaviour of the fans at his home stadium.
"I was surprised because I've never heard it before when playing here. But I think it is something that the FA and world
football are trying to cut out," the Real Madrid midfielder told reporters.
"When it happens in football all around the world of course you feel ashamed...it wasn't good tonight, but as I say people
are working hard to cut it out.
"The players have had this before and they just get on with the game and they are strong enough to handle this."
