Title-holders Mamelodi Sundowns of South Africa are among eight winners of the CAF Champions League who will compete in the premier African club competition next season.
The draws for the 2017 preliminary and first rounds are scheduled to be made in Cairo Wednesday, officials from several national football associations told AFP.
Only Al Ahly of Egypt, TP Mazembe from the Democratic Republic of Congo and Enyimba of Nigeria have staged successful defences since the 1964 launch of the Champions League.
Ahly (2005-2006 and 2012-2013) and Mazembe (1967-1968 and 2009-2010) twice won back-to-back titles.
Enyimba, the only Nigerian outfit to conquer the continent in the premier club competition, triumphed in 2003 and 2004.
A further eight defending champions reached successive finals, but had to settle for runners-up prizes.
Record eight-time title-holders Ahly, fellow Egyptian side Zamalek and Esperance and Etoile Sahel of Tunisia are among the teams who will challenge Sundowns, the second African champions from South Africa after Orlando Pirates.
