Love, who played for Angola at the 2006 World Cup in Germany, scored in the 24th minute to reduce the overall lead of the Tanzanians.

Medeama of Ghana booked their place in the group phase after an impressive 2-0 win over South Africa's Mamelodi Sundowns in Sekondi which put the hosts through on the away goals rule.

But a penalty from Malik Akowush followed by a Bernard Ofiri goal made it 3-3 on aggregate, and gave Medeama an away goals victory.
Al Ahly Tripoli of Libya scored a late equaliser in Egypt against Misr Elmaqasah to progress, also on away goals. Ghanaian Nana Poku gave Elmaqasah an early lead, which they held onto until the last five minutes of the game before conceding a penalty, which was converted by Zakareya Al Lafy.
Penalties were decisive in Morocco where Kawkab Marrakech scored two of them to beat Sudanese giants Al Merreikh. 2-0 it finished to the home team, to take them through 2-1 on aggregate.
And there will be two Moroccan sides in the draw on 24 May, because FUS Rabat put in a fine winning performance at home against Stade Malien - taking the game 4-0.
