African Confederation Cup comeback specialists Enyimba of Nigeria must pull another rabbit out of the hat Sunday to reach the group phase. The team from south-east city Aba overcame two and three-goal deficits in previous rounds before suffering a 4-0 drubbing from Zambian bank club ZANACO in Lusaka two weeks ago in the first leg of a final-round qualifier. That result leaves the 'Peoples Elephant' needing to score four unanswered goals just to force a penalty shoot-out and only one club has managed to wipe out such a deficit since the Cup was launched six years ago. Mount Cameroon trounced South Africa visitors Ajax Cape Town 5-0 in a 2008 qualifier after suffering a 5-1 first-leg loss on the southern tip of the continent. Ajax assumed they were through after the first match and sent a weakened squad to central Africa - a mistake ZANACO coach and former Zambia striker Wedson Nyirenda is determined to avoid. 'The squad has been warned about complacency after building a healthy lead at home. It is not going to be an easy game,' he stressed ahead of a clash between clubs appearing in the competition for the first time. 'We are ready for any hostility Enyimba might put us through. I know what can happen in west Africa,' he said referring to the often poor treatment visiting football clubs receive in Nigeria. SuperSport United of South Africa claimed they were fed a bread-only lunch before a Champions League game this year and more recently Al-Ahly of Egypt resorted to training in a hotel garden because of sub-standard facilities. Winners of back-to-back African Champions League titles this decade, Enyimba received a few timely boosts this week by reaching the Nigerian FA Cup final and passing striker Junior Osagie fit. Osagie and Kalu Uche shared the six goals that took the new Nigerian champions past Academica Soyo of Angola and Vita Club of the Democratic Republic of Congo with the latter tie settled by a shoot-out. 'We erased the word 'impossible' for our dictionary a long time ago and this philosophy has helped us win many matches in Africa,' boasted Enyimba coach Felix Emordi. 'My boys are responsible for the situation we find ourselves in, but I am happy that they have woken from their slumber,' said the man who guided the 'Peoples Elephant' to their second Champions League triumph. SuperSport must defend a 2-1 advantage over FUS Rabat in Morocco with only 13 footballers, including third-choice goalkeeper Jacob Mokhasi, owing to a spate of injuries and domestic close-season transfers. Regular goalkeeper Emille Baron is recovering from an injury that kept him out of the World Cup and Uganda-born reserve Denis Onyango has switched to another South African Premiership club. The eight survivors after the fourth round are split into two groups with a six- round schedule kicking off mid-August in pursuit of a 660,000-dollar first prize.
