Aggregate 2017 and 2018 table
As Toronto FC won MLS Cup 2017, one of the U.S. berths for the 2019 CONCACAF Champions League had to be reallocated, to the U.S. non-champions with the best aggregate record over the 2017 and 2018 MLS regular seasons. As the top ranked team in the table, Atlanta United FC, also qualified for the Champions League by winning MLS Cup 2018, the Champions League spot via the aggregate table was instead awarded to the second-placed team, the New York Red Bulls.[2][3]
