Ghana and Nigeria renew their rivalry in the WAFU Cup of Nations semi-finals Thursday with either side hopeful of reaching the finals.Thursday's meeting tops the fixtures of the regional championship in Nigeria as Togo and Liberia play in the other game.For Nigeria coach, Samson Siasia, his side remains unfazed about the prospect of playing Ghana as David Duncan's team are seen as the biggest threat to the Nigeria's title-winning ambitions."Our objective is to get to the final. It doesn't matter if we are playing Ghana or Togo," the Nigeria coach said. "We are playing a match that we want to win, and who we play against is not the issue."What is important is if we play the way we want to play and do the right things on the field."The winners of the last-four fixtures will play in Saturday's finals while the losers engage each other in a third-place play off on the same day.Source: Ghanafa.org
