The veteran Swedish magician, 37, took home the matchball as he fired his side to a 3-2 win over their city rivals.
The pre-match talk was dominated by Ibrahimovic’s taunting of LAFC’s Carlos Vela, who leads the race for the MLS golden boot, for playing in the States during his peak years.
Ex-Arsenal starlet Vela, 30, broke the deadlock at Dignity Health Sports Park before the former Manchester United, Barcelona, Inter and AC Milan star took over.
He fired in a treble to put Galaxy 3-1 ahead with Vela pulling one back in injury time.
But members of the opposition coaching staff were furious with Ibra for an alleged elbowing incident from earlier in the match.
LAFC goalkeeper coach Zak Abdel led the protests following the final whistle – but he was met with an angry response from the big striker.
Ibrahimovic said: “Go home, you little bitch. Go home.”

He could now face disciplinary action from MLS chiefs over his actions.
Galaxy’s victory cut the gap at the top of western conference to nine points.
