Not sure how this new format in terms of friendlies relates to the qualification process of Euro 2020 but I am led to believe the winners of each League get a play off place. Proper qualification for Euro 2020 does not start until March 2019.
LEAGUE C (teams to be split into one group of three, and three groups of four)Romania, Scotland, Hungary, Slovenia, Albania, Montenegro, Serbia, Greece, Norway, Israel, Bulgaria, Finland, Cyprus, Estonia, Lithuania
