Toronto FC are returning to the MLS Cup for a third time in four years.

Substitute Nick DeLeon scored the game-winning goal with a beautiful strike in the 78th minute, giving the Reds a 2-1 victory over defending champion Atlanta United in the Eastern Conference Final from a packed Mercedes-Benz Stadium.

Toronto will battle the Seattle Sounders once again in the MLS Cup as the two sides split their first two final clashes in 2016 and 2017.

The MLS Cup goes Nov. 10 from Seattle.
