Atlanta United supporters set the tone for a convincing 3-0 victory over New York Red Bulls in the first leg of Eastern Conference finals, with a stadium-wide tifo display.

The tifo involved over 70,000 supporters inside the Mercedez-Benz Stadium, who recently broke MLS total season attendance figures with over 900,000 fans attending games this season.

The Five Stripes have put themselves in prime position to reach the final of the MLS Cup for the first time with their 3-0 victory. 

Atlanta United players showed their appreciation for the tifo on Twitter.

The second leg against New York Red Bulls is set to be played on Friday 30 November at 11:30 am (AEST).

Atlanta United will be looking to see out their three-goal lead to face either Sporting Kansas City or Portland Timbers in the final.
