A brace from Rwanda's Jacques Tuyisenge helped the hosts secure a memorable win, having gone behind early on.

Zamalek went ahead after seven minutes through Egypt's Ibrahim Hassan who struck from outside the box.

Gor worked hard for an equaliser with Tuyisenge scoring the first of his two goals 18 minutes later.

The Rwanda international found the back of the net again with a 38th minute header to put the Kenyan side 2-1 up, but that advantage only stood for six minutes.

Ibrahim Hassan, who scored Zamalek's opener, pounced on a Gor mistake and found the back of the net to make it 2-2 going into the break.

In the second half, Nicholas Kipkirui made it 3-2 to Gor after 51 minutes, and the hosts withstood an onslaught of Egyptian pressure to seal the victory in stoppage time through the experienced Dennis Oliech who made it a famous 4-2 win for the Kenyan side.

The result put Gor Mahia top of Group D ahead of the late kick-off in Algiers between NA Hussein Dey and Angola's Petro Atletico.
