7. The 2019 MLS Cup
To call the following few years 'barren' for the Sounders would be harsh, but for a city suddenly used to success (at CenturyLink Field at least, sorry Mariners fans) the club seemed to be underperforming.
Well into a still-active run of second placed finishes in the Western Conference regular season standings, consistent good play took a while to translate into silverware. A repeat of the 2016 MLS Cup the following year saw them defeated by Toronto, paired up with early US Open Cup exits and mediocre showings in the CONCACAF Champions League.
It's hard to keep a good team down for too long though, and nearly 70,000 fans packed into their home stadium to watch a comfortable 3-1 win over Toronto (yes, Toronto again!) to lift the team's second MLS Cup – and astonishingly, their first ever trophy without Osvaldo Alonso in the starting lineup.
8. The 2022 CONCACAF Champions League
This wasn't supposed to happen. Seriously, in the 13 previous years of the CCL in its current form, nine of the finals didn't ever feature a team from outside of Mexico. MLS clubs had made it to two of them, and were both beaten by...Mexican clubs.
Nevertheless, the Sounders packed up and headed off for their first leg at the Estadio Olimpico Universitario, where two late penalties from Nicolás Lodeiro (including one in the ninth minute of injury time) saved a 2-2 draw after being outplayed for most of the 90 minutes.
There was only cautious optimism for the second leg at Lumen Field, but a strike late in the first half from Raul Ruidiaz calmed some Seattle nerves.
If that goal calmed the crowd, his second – ten minutes from full time – sent them wild, all-but guaranteeing the Sounders their first ever continental title, which Lodeiro put the stamp on eight minutes later with the goal to make it 5-2 on aggregate.
