The Crew has a goal to sell out all 17 regular-season home games. It’s one the club won’t achieve in 2017, as 15,023 was the announced attendance for a chilly home opener against Chicago and 11,067 attended last Saturday’s game against Portland. (The official capacity of Mapfre Stadium is 19,968.) Still, Loughnane said, the club hopes to set attendance and home sellout records for a fourth straight season. Last year, the team’s average attendance was 17,125 and it sold out six games.
