PORTLAND, Ore. (AP) — This summer showed Major League Soccer that attracting U.S. fans to the game is no longer an issue. It’s engaging them that the league sees as its next step.

MLS wrapped up its All-Star game celebration Wednesday night with a 2-1 victory over German power Bayern Munich.

The match at Portland’s Providence Park capped a wildly successful few months for the sport stateside, following the U.S. national team’s run to the round of 16 in Brazil that drew record television ratings.

And it was certainly not lost on the league when an exhibition match between Manchester United and Real Madrid drew nearly 110,000 fans at the Big House in Michigan last week.

MLS is poised to expand to 24 teams by 2020, with a focus on steady — but not too rapid — growth.
