Why did it matter where a club finished in the table?
The league placings created the knockout bracket and the new “seeding” system means the highest-placed teams can’t face each other until the latter stages of the knockout round.
For instance, if we look at the final table, Lazio and Athletic Club finished in first and second and can’t play each other until the final. The teams in third and fourth — Manchester United and Tottenham Hotspur — can’t play Lazio and Athletic Club until the semifinals.
All paired teams, such as Man United and Tottenham, cannot meet until the final and have the same possible round-of-16 opponents: Real Sociedad, Galatasaray, AZ Alkmaar and FC Midtjylland.
