Major League Soccer returned to action this week for its 22nd season and it did not disappoint. It came fully equipped with new teams, new stadiums, and new excitement.

Two more United’s joined the league, Atlanta and Minnesota, although both debut’s resulted in a loss. Orlando City SC unveiled a beautiful new stadium complete with the Purple Wall and it was loud. Striker Cyle Larin summarized it with a smile after the match:

It was loud. It was loud. I’ve never seen anything like that before. They were there from the first to the last minute.

The weekend was full of entertainment. Even the scoreless draws provided plenty of excitement and awe (see DC United vs Sporting KC). All but one match was decided by one goal or less and although it’s still early to make many predictions, week one still provided some potential talking points.

Lets look at five things we learned from MLS week one.
