The duo are currently four goals behind Kariobangi Sharks striker who top the chart with 17 goals.
Aswani will have to do much more by shaking the net five times against Sharks and hope that his defenders keep Masoud at bay on Saturday when the shoppers entertain Sharks in the season-ender at Ruaraka Grounds.
Rwandan international, Tuyisenge will also be hoping to put five goals past Sony Sugar goalkeeper in order to snatch the coveted trophy off the face of Masoud should he not score over the weekend.
