I give it a try ... I know that in Africa the "home factor" is very important and often decisive but I have some info here ..
Gor Mahia (Kenya) will be without some very important players in the first leg against Berkane, in fact they will be out of the game: Captain Harun Shakawa, and the top-scorer the Rwandan Tuyisenge. These 2 absences are added to other 2: the midfielders Wendo and Batambuze. Maybe Berkane has any chance of getting results here.
Can you drop some sources please because I couldn't verify the missings with mines
