It has been a good start for Abdul Karim Zito's side, who have won two games and drawn the other ahead of matchday four's fixture at the Cape Coast Stadium.
“It is going to be a tough game for us," Sharani told footballmadeinghana.
"We beat them in the [Ghalca] Top Eight [championship] and they are in for a revenge.
"Also, they are not faring well this season and they will want to beat us to get on track.
"However, it's a must-win game for us and we will beat them to maintain our [unbeaten] streak."
On individual note, Sharani has been one of the early revelations of the season, having netted twice and picked up two Man of the Match accolades thus far.
“Personally, it has been a perfect start for me in the topflight," the attacker, whose performance has earned him a call-up to Ghana's under-20 side, said.
"This was what I wanted. It's a dream start for me and I hope to continue.
“The Ghana Premiership is a tough league and the tempo is very high.
"My desire to play at the highest level has been my motivation in this first season in the elite division."
Dreams currently sit third on the league table.
