Gamba edged out Oita Trinita 1-0 in their most recent league outing.
Olunga scored his 22nd goal in the league in Kashiwa’s last fixture which Nelsinho’s men lost 3-2 against Shonan.
Michael Olunga’s Kashiwa Reysol will hope to replicate the magic moments they have had against Gamba Osaka when the two sides clash in Japan’s top-tier league in at Panasonic Stadium Suita on Saturday.
Eight points separate the two sides, with Gamba occupying the fourth spot on 45 after going on unbeaten in eight matches.
