Ghana coach Claude LeRoy said he would have to put his personal emotions aside when his side meet Cameroon in the African Cup of Nations semi-final on Thursday. The French managed guided The Indomitable Lions to Nations Cup triumph in 1988, but now he will have to confront them for a place in the final. "I will put my feelings aside during the 90 minutes. I've had great times with Cameroon but I am now the Ghana coach," LeRoy said. "Feelings will be for before and after the match," he was quoted as saying by Ghana Football Association website. LeRoy believes tournament hosts Ghana have reached the most difficult stage, where surprises often occur. "In every big competition, the hardest part is always the semi-final. The semi-final is always the most difficult step to climb." "Remember the 1988 Nations Cup: hosts Morocco lost to Cameroon in the semis and at the last World Cup, (hosts) Germany thought they had done the hardest part but eventually lost in semi-final." Ghana faced Cameroon twice in 1982 and 2000. Honors were even in both matches.
