Despite losing the lead twice to archrival LA Galaxy in the Western Conference semifinals, Los Angeles FC lived to talk about it on Thursday night.

Cristian Arango scored three minutes into second-half stoppage time to lift the Supporters’ Shield winners to a 3-2 win over the Galaxy in the MLS Cup Playoffs before a crowd of 22,305 in a postseason edition of El Trafico at the Banc of California Stadium.

LAFC will play the winner of Sunday’s semifinal game between Austin FC and FC Dallas in the conference final on Sunday, Oct. 30.

It was a see-saw match.

Denis Bouanga, off a Carlos Vela assist, scored his first goal of the contest to give the hosts the lead in the 23rd minute, but the Galaxy equalized in the 44th minute behind Samuel Grandsir.

Bouanga boosted LAFC into the lead again in the 80th minute off a Kwadwo Opoku assist.

The Galaxy, however, knotted things up yet again, this time on a goal by Dejan Joveljic in the 85th minute, leaving the heroics to Arango, an MLS MVP finalist.
