This match has been described by Finland boss Markku Kanerva as "probably the most important game in Finnish football history".
Finland can secure a place in the last 16 with a win and history is on their side, having won four and drawn three in their last seven meetings against Belgium.
Belgium sit top of the group knowing that a point can cement that spot.
Kevin De Bruyne, Eden Hazard and Axel Witsel are tipped to make their first starts at EURO 2020.
