SOGWIPO, South Korea -- Germany might be penalized by refereeing mistakes when they face co-hosts South Korea in Tuesday's World Cup semifinal but will not let that affect them, Captain Oliver Kahn said on Sunday.

"We may have one or two refereeing decisions against us," said the Germany goalkeeper, who has been instrumental in the triple champions' run to the last four. "That's normal. It's called home advantage. If it happens, we must not let it demoralize us. If we have a goal disallowed, we must concentrate on scoring another one." FIFA said on Sunday that referees had made "one or two major mistakes."
