Wales take on Finland in a final-game shootout at the Cardiff City Stadium to determine which side earns promotion from League B Group 4 in the UEFA Nations League.
The hosts are top of the standings with 13 points from five matches, one point better off than opponents Finland, whom they beat 1-0 in the reverse fixture two months ago.
Match preview
Continuing with the theme of their entire campaign to date, Wales produced an underwhelming display in Sunday's clash with Republic of Ireland but still got the job done.
David Brooks scored the only goal of the game in what was the sixth meeting between the sides in three years, ensuring that the Dragons are in control of their own destiny.
All four of Wales's Nations League victories have come by the same 1-0 scoreline, although they are usually made to wait until later than the 66th minute to find the breakthrough.
The win over Republic of Ireland makes it one defeat in 13 matches for Wales - a 3-0 friendly loss to England last month - in a run stretching back to June 2019.
In competitive matches, it is seven games without a defeat for Wales, keeping a clean sheet in each of those games in what is their best ever defensive streak.
Another clean sheet on Wednesday will guarantee promotion to League A, with Wales - managed by Robert Page in the absence of head coach Ryan Giggs - only requiring a point.
Finland have had a near-perfect campaign of their own, the only blemish being a late 1-0 loss to the Dragons when the sides met in Helsinki on September 3.
Not only have the Eagle-Owls won all five Nations League games since then - conceding just once - they also beat France 2-0 last week in a shock friendly result.
Indeed, Markku Kanerva's men found life a little tougher away to Bulgaria on Sunday, hanging on to secure a 2-1 victory that keeps them hot on Wales's heels.
Finland must now beat Wales - something they have only achieved four times in 13 previous attempts - if they are to leapfrog their opponents and claim top spot.

Despite Jose Mourinho airing his concerns over Gareth Bale's fitness, Page played the Tottenham Hotspur forward for the full 90 minutes against Republic of Ireland.
Given the importance of this home clash with Finland, stand-in Wales boss Page is almost certain to start Bale once again on Wednesday, with minimal changes expected.
Wales went with a back five last time out, with Rhys Norrington-Davies and Neco Williams in the wing-back positions, but they may revert to a back four in midweek.
Matthew Smith is pushing for a recall in holding midfield, likely in place of Joe Morrell, while Kieffer Moore seems likely to get the nod up top.
As for Finland, they lost Joel Pohjanpalo to an injury in the first half of their victory over Bulgaria in Sofia, with Marcus Forss brought on in his place.
That could be a big blow for the visitors, especially with Teemu Pukki scoring only once in five Nations League outings to date.
Ilmari Niskanen and Rasmus Schuller are also contenders to start after being brought off the bench against Bulgaria at the weekend.
Wales possible starting lineup:
Ward; Roberts, Mepham, Rodon, Davies; Ampadu, Smith, Brooks; Bale, Moore, James
Finland possible starting lineup:
Hradecky; Alho, Toivio, Arajuuri, Uronen; Lod, Sparv, Kamara, Taylor; Pukki, Forss
We say: Wales 0-0 Finland
Wales have kept five clean sheets from five in League B Group 4, while Finland have shipped only two goals so far.
The visitors enter this game in good form on the back of last week's stunning win over France and narrow victory over Bulgaria, but the Dragons know a point will do and should have enough to grind out a draw.
