Traditionally, Swazi clubs are seen as cannon fodder in CAF competitions, but Swallows bucked the trend last season by giving Zambian outfit Zanaco a scare.

The Ugandans shocked seasoned campaigners El-Merrikh 2-0 in Sudan with two goals in as many minutes midway through the opening half. Herman Wasswa broke the deadlock and Tony Odur added the second while Merrikh failed to convert a penalty during relentless pressure after half-time.
Another unexpected result came off the west coast in the Portuguese-speaking island state of Sao Tome e Principe with Sporting Praia Cruz winning 3-2 against Malians Stade Malien.

FAR were among six former Champions League title-holders in action and the other five triumphed with Raja Casablanca of Morocco the most impressive. The 2013 FIFA Club World Cup runners-up to Bayern Munich crushed Sierra Leone visitors Diamond Stars 6-0, with four goals coming from Mouhcine Iajour.

Nigerians Enyimba, the 2003 and 2004 title-holders, left it late to build a 3-1 home advantage over CAF rookies Anges Notse of Togo.

Kingsley Sokari and Gwar then scored the goals that should ensure the 'People's Elephant' survive the return match in Lome.
Fellow Nigerians Kano Pillars were less successful, having Bello Kofarmata sent off in a 3-1 defeat away to 1973 champions Vita of the Democratic Republic of Congo.
