Senegal's showdown with Japan on Sunday could prove pivotal in Group H.
The Lions of Teranga opened their World Cup campaign with a superb 2-1 win against Poland, just hours after the Blue Samarai put ante post group favourites Colombia to the sword.
Victory for either team here will put them within touching distance of a place in the last 16, as with Poland and Colombia due to meet later in the day, three points here could be enough to guarantee progression.
It is Senegal who are bet365's 11/8 (2.38) favourites to claim a vital victory, while the odds compilers offer 5/2 (3.50) that Akira Nishino's team come out on top.
A draw would leave both teams on edge ahead of their final group games and bet365 go 21/10 (3.10) that the match ends all square.
Liverpool's Sadio Mane and Everton's Idrissa Gueye will surely start for the Senegalese, while West Ham's Cheikhou Kouyate - Senegal's captain - may have to settle for a place on the bench once again.
Shinji Kagawa and Yuya Ozako were Japan's goal heroes against Colombia and both men are expected to start for the Blue Samarai.
Both teams celebrated a 2-1 win on Tuesday and bet365 go 10/1 (11.0) that the Lions of Teranga repeat that scoreline here, while the same firm go 14/1 (15.0) that it is Japan who win 2-1 this weekend.
The odds compilers go 6/4 (2.50) that there are at least three goals in this game, while the same firm offer 21/20 (2.05) that both teams are on target.
Japan will have been delighted with their 2-1 win against Colombia, but Nishino's side laboured at times, despite the South Americans being reduced to 10 men inside three minutes.
Senegal produced a powerful performance to see off Poland and the Lions of Teranga could be celebrating their first World Cup finals win against non-European opposition this weekend.
The 11/8 (2.38) quote from bet365 for Aliou Cisse's side to claim all three points may represent good value for punters ahead of Sunday's crucial clash.
