Asamoah, who in 2001 became the first black to represent Germany, was subjected to racist taunts by fans of Hansa Rostock's second team in Schalke's first round cup win on September 9.

Hansa were fined 20,000 euros for the conduct of their fans but Asamoah said the abusive supporters faced ruining all the good public relations work from this summer's World Cup.

"A lot of people abroad associate Germany with xenophobia. But at this summer's World Cup everyone was astonished that Germans could be so different," Asamoah said in an interview with Kicker magazine.

"In Ghana the people were thrilled and maybe a bit relieved. But what happened to me in Rostock was broadcast throughout Ghana on the radio. It also reached other countries and the people were horrified.

"The ape noises have changed how people look at Germany in some parts of Africa. Those idiots are responsible for that."

The 27-year-old Asamoah, who will miss most of the season after suffering a horrific double leg fracture, also said he had experienced racism off the field.

"I have had problems in Gelsenkirchen too. I wanted to go to a disco with my brother and another African. Three Africans? We did not get in," Asamoah explained.

Asamoah revealed that the people responsible were then willing to let him in when they recognised that he was a famous footballer.

Asamoah has not encountered any racism while playing for his adopted homeland Germany but admits he would consider retiring if that changed.

"I would have to ask myself whether it makes sense to play for Germany," he said.
