After a lackluster performance in the early matchdays and significant offensive futility, Wales take all 6 points on the last two match days, get the final of the 20 spots, and avenge their earlier defeat to Hungary. Aaron Ramsey plays in his first match (I believe) in qualification and looks like anything but a guy who hasn't played in forever -- arguably the man of the match.
This also means the 16 playoff teams, from which the last four qualifiers will come, now are set in the most complicated tournament of all time. But while the 16 teams are known, the matchups for the playoffs won’t be set until a draw on Friday. There are four groups (“paths”) of four teams each. One team from each group advances to the finals through a head to head four team bracket playoff in March 2020. Some teams are set in a path, and others will need to be drawn. The draw happens in reverse order, from League D to A. Path D is set. Path C is mostly set. Paths B and A will be largely determined by draw. Once the four teams are set in a "path," the seeding for the playoff is determined by ranking.
Path D: Georgia, North Macedonia, Kosovo and Belarus.
Path C: Scotland, Norway, Serbia and one of Bulgaria, Israel, Hungary or Romania, to be determined by draw. The three not drawn will move to path B.
Path B: Bosnia and Herzegovina is locked into the top spot. The other three will be drawn from a pot of the three that moved up from Path C, plus Slovakia, Ireland, and Northern Ireland. (So, there’s a good chance of Ireland and Northern Ireland being in the same group. If they both get drawn into path B, they likely would be 2 and 3 in the group and so end up playing the first group semi in Dublin. if they move up to path A, they probably would not face each other until the final if they both advance. I think they played a friendly last year, but it has been a while since they played each other in competition.) The three that don’t get drawn into Path B move up to Path A.
Path A: Iceland and three not drawn into Path B.
Edit: Just read, actually, that UEFA (of course they have) have reserved the right to manipulate the playoff draw to give as many host teams -- so, Hungary, Ireland, Scotland, and Romania -- a favorable chance to qualify. such bullshit. But the "draw" may not be a simple draw.
