The Slum Boys are expecting to have Clifford Alwanga available for the next to-tier assignment
Mathare United head coach Frank Ouna believes the difference between them and AFC Leopards during Thursday's 1-0 defeat was the fact that the latter utilised their chance while they did not.
The 2008-league champions fell by a solitary goal scored by Elvis Rupia in the Football Kenya Federation Premier League game.
The Slum Boys finished the game with 10 players and the tactician has also commented on the second-half incident which led to David Ochieng's red card.

"Thursday's game was the proverbial game of two halves where Leopards dominated the first half and scored from a half chance," Ouna told Goal.
