Match preview
Throughout the knockout phase of this competition, the Los Angeles attack has stepped it up, outscoring their previous three opponents by a combined margin of 9-1.
Steve Cherundolo's men come into this encounter without a defeat in normal time at BMO Stadium since being clobbered 5-1 by the Columbus Crew in July.
Since suffering a 2-0 defeat at Minnesota United in March, this group have scored in every one of their competitive fixtures.
This team always seem to shine in transitional moments, producing multiple goals off counter-attacks at this tournament with plenty of quality to make those chances count.
Not since a 3-1 defeat versus the San Jose Earthquakes in early May have we seen this side lose in normal time against a team from the Western Conference of Major Leagues Soccer (MLS).
LAFC have not lost a semi-final affair in any competition since the Houston Dynamo beat them on penalties (10-9) at the 2018 US Open Cup.
The Rapids have been down many times in the 2024 Leagues Cup but never out, coming back to win two matches in this tournament when conceding first.
Chris Armas's side have won two of their encounters at this tournament on penalties, with all of their victories being either in a shootout or by a single goal, including their upset over Club America when that match wound up 0-0 after 90 minutes.
This is the furthest they have gone in a major competition since making the 1999 US Open Cup final, losing to the Rochester Rhinos on that occasion (2-0).
Colorado have yet to win a Leagues Cup contest away from home within 90 minutes, with their victory this past weekend being their first outside Dick's Sporting Goods Park in this competition.
The Burgundy Boys have only beaten one MLS side in their previous four games against them, defeating Real Salt Lake at the Rocky Mountain Cup 3-2 in July.
They have lost all six of their away matches versus Los Angeles FC, losing the last three against them by a combined margin of 10-0.

We say: Los Angeles FC 3-1 Colorado Rapids
The Rapids have fought valiantly to get to this stage, but the Black and Gold rarely lose at home and have so many attacking options to call upon that we believe it will all be too much for Colorado to handle.
