Midtylland are champions of Denmark, they were tied with Brøndby going into the final matchday but needed a better result because their goal differential was worse. Things looked pretty bad early on because they were down 0-2 at home to Silkeborg while Brøndby were leading AGF 1-0. Then at the start of the 2nd half Midtjylland scored 3 goals in 6 minutes while Brøndby conceded twice, tied it, then conceded again. So with Brøndby losing, Midtjylland needed to avoid defeat which they did (although they did concede an equalizer) and so they beat out Brøndby by 1 point.
In Poland, Jagiellonia Białystok won their first ever title, one year after finishing 14th(!). They were level on points with Śląsk Wrocław but had the better h2h result. Polish league seems pretty wide open because 5 teams have won the title in the past 6 years, Legia Warszaw twice, Lech Poznan once, and both Jagiellona, Rakow (last year) and Piast Gliwice (2019) won their first championships.
