The group phase of the African Champions League reaches its midway point on Sunday.
Morocco's Wydad Casablanca host defensively strong Esperance of Tunisia in Group B.
Egypt's Al Ahly put themselves back in the frame in Group B with a 2-0 win over Mouloudia Alger on Friday.
In Group A meanwhile Enyimba of Nigeria host Morocco's Raja Casablanca and Cotonsport of Cameroon host Al Hilal of Sudan.
Wydad have been in prime form in the tournament, hitting seven goals in their two games so far, but they have also conceded three, so Esperance will be keen to exploit that weakness.
The Tunisians are also very strong defensively - they have conceded only three goals in six qualifying and group matches.
But Wydad will be counting on strikers Mouhssine Iajour and Congolese Fabrice Ondama to break Esperance's resolve.
Enyimba of Nigeria - one of only three teams to successfully defend the title since its 1964 inception - and twice runners-up Al Hilal of Sudan have set the Group A pace with four points each.
Both enjoy home advantage on Sunday with Enyimba facing goal-shy Raja Casablanca of Morocco in south-eastern city Aba while Al Hilal confront 2008 runners-up Coton Sport Garoua of Cameroon in sauna-like Omdurman.
Kalu Uche could pose the biggest threat to three-time African champions Raja after bagging a brace in Garoua while Cotonsport must contain Zimbabwean Edward Sadomba after he scored three times in two group matches.
