The Gunners’ record signing from Lyon was brought off the bench at the ANZ Stadium and showed what £52.6million gets teams in the market.
With seven minutes left on the clock he sidefooted home after Alex Iwobi teed him up with a cross.
The France striker showed his team-mates how to stay cool in front of goal as they wasted chance after chance and were kept out by Sydney keeper Andrew Redmayne.
Before Lacazette struck, all they had to show for their efforts was Per Mertesacker’s early strike.
