Wales became the 20th and final side to seal automatic qualification to Euro 2020 on Tuesday night after two goals from Aaron Ramsey sealed a 2-0 win over Hungary.
The two teams in each of the 10 groups that finished as winners and runners-up, guaranteed their place at next summer’s tournament.
However, there are still four places up for grabs at Euro 2020, which will be contested by 16 teams, split into four groups of four.
Sportsmail explains which teams have secured a play-off spot and the play-off process facing the remaining sides vying for their place at Euro 2020.

Path B: Bosnia and Herzegovina, Slovakia, Republic of Ireland, Northern Ireland
Path C: Scotland, Norway, Serbia, Bulgaria, Israel, Hungary, Romania
Path D: Georgia, North Macedonia, Kosovo, Belarus
*A draw will decide which of Bulgaria, Israel, Hungary or Romania would fill the empty slot in Path C, and which three would go into Path A.
How do the play-offs work?
Eligibility for the play-offs is based on the performance of the remaining nations during the Nations League groups.
In case you’d forgotten, there were 16 groups of four teams, with a qualifying spot assigned to each group, given to the team who finished top.
But a host of teams have already qualified after finishing in the top two places of their Euro 2020 qualification group.
If a team has already secured a play-off spot via their Euro 2020 group, their play-off place is given to the next best ranked team in their Nations League tier.

Euro 2020: Nations League A
All of the teams above, with the exception of Iceland, secured their place at Euro 2020 by finishing as winners or runners-up of their Euro 2020 qualification group. That means the play-off spot in Nations League A was passed down to Iceland.
The four teams who won their respective Euro 2020 groups – Holland, England, Switzerland and Belgium, were guaranteed a play-off spot thanks to their Nations League performance, meaning their play-off spots were passed down to the best ranked teams in Tier B…

How will the play-off ties be decided?
Teams will now be split into four play-off paths of four teams. Path A features the strongest teams, through to Path D, which includes the lowest ranked nations.
The highest-ranked team in each path will play at home against the country ranked fourth, with the nations placed second hosting the third-placed teams in the other semi-final.
The play-offs won’t be two-legged affairs, these will be single-leg knockout matches, with the highest-ranked teams hosting each semi-final.
Uefa could still fiddle with which teams are placed in each path to give next summer’s host nations a better chance of qualifying. A final draw is expected to be made by Uefa’s emergency panel on Thursday.
