Zimbabwe and Mozambique established two-goal first leg advantages on Sunday in pursuit of 2013 Africa Cup of Nations places. The often wasteful Warriors of Zimbabwe exhibited clinical finishing to beat Angola 3-1 in Harare while the Mambas (Snakes) of Mozambique netted twice during the second half for a shock 2-0 victory over former champions Morocco in Maputo. Algeria snatched a last-minute goal to defeat Libya 1-0 in Moroccan city Casablanca, Guinea won by the same score at home against Niger and the Democratic Republic of Congo outclassed Equatorial Guinea 4-0 in Kinshasa. Zimbabwe and Mozambique are rare participants in the premier African national team championship and their presence would be welcomed by hosts South Africa with the prospect of many supporters travelling from the neighbouring states. Angola and Morocco will enjoy home advantage in the mid-October return matches and the aggregate winners will be among 15 teams who join automatic qualifiers South Africa for the three-week tournament next January and February. Mateus Galiano da Costa conceded an early own goal before a Khama Billiat shot and an Archieford Gutu header gave Zimbabwe a three-goal half-time lead that was trimmed early in the second half when Djalma Campos scored. It was a competitive baptism of fire for Uruguay-born Black Antelopes coach Gustavo Ferrin, although the away goal will give the Angolans some hope for the second leg in Luanda. Mozambique wasted several chances that triggered the constant booing of striker Jerry Sitoe before Almiro Lobo broke the deadlock and Elias ‘Domingues’ Pelembe got a potentially crucial second goal in stoppage time. Algeria won more possession in the North African derby switched from Tripoli to Stade Mohammed V in the Moroccan commercial hub because of the unstable security situation within the Libyan capital. But a match watched by a small crowd appeared doomed to end goalless until El Arbi Hilel Soudani struck a low shot into the corner of the net for his second goal of the qualifying competition. DR Congo are virtually assured of returning to the Cup of Nations after a seven-year absence thanks to the whipping of 2012 co-hosts and quarter-finalists Equatorial Guinea. It was one-way traffic toward the Equatoguinean goalmouth from the kick-off with the Congolese forcing 11 first half corners.
