The hosts are without a victory in their last seven meetings against the visitors, losing five and drawing the other two, which makes this fixture a tricky one for them.
Match preview
Seattle Sounders found their form in late March, igniting a winning streak that they will look to extend beyond Sunday's clash.
Even more impressive, the Sounders are unbeaten in all competitions since a March 9 defeat away to Kansas City, recording seven wins and a draw in eight games since then, including a 2-1 US Open Cup victory over Sacramento Republic.
Brian Schmetzer's men coolly dispatched St. Louis in their most recent league match, scoring a goal in each half to secure a 2-0 victory at Lumen Field.
This win propelled the Rave Green to sixth place in the Western Conference of the MLS table, one point ahead of Portland, who occupy the final guaranteed playoff spot.
However, their impressive run faces a stern test against one of the league's best teams this season, a side they last beat in 2021, failing to win in the last three times they hosted this fixture, drawing twice and losing most recently.
Meanwhile, LAFC are yet to fully recover from a humbling 5-1 defeat at the hands of Columbus, as they could only manage a 1-1 draw against fellow top-three contenders, Real Salt Lake.
Steve Cherundolo's side were on a remarkable run before their last two matches, recording 12 victories and a draw to go on a 13-match unbeaten streak across all competitions.
These recent results have seen the Black and Gold surrender top spot in the Western Conference, as they now sit two points behind LA Galaxy.
Despite boasting the best home record across both conferences, LAFC's last two winless matches have come on home soil, and they will be hoping a return to the road can help them end this mini-slump.
Cherundolo's men are unbeaten in their last six away matches, which includes five wins and a draw, a record they will hope to extend against Seattle.
