Аннотация: We evaluate the sporting effects of the seedingsystem reforms in the Champions League, the major footballclub tournament organized by the Union of EuropeanFootball Associations (UEFA). Before the 2015–2016 season,the teams were seeded in the group stage by their ratings.Starting from the 2015–2016 season, national championsof the Top-7 associations are seeded in the first pot,whereas other teams are seeded by their rating as before.Taking effect from the season 2018–2019, the team’s ratingno longer includes 20% of the rating of the associationthat the team represents. Using the prediction model,we simulate the whole UEFA season and obtain numericalestimates for competitiveness changes in the UEFA tournamentscaused by these seeding reforms. We report onlymarginal changes in tournament metrics that characterizeability of the tournament to select the best teams andcompetitive balance. Probability of changes in the UEFAnational association ranking does not exceed several percentfor any association.
