Veteran striker Derbyshire seized upon a slack pass to dink home a cheeky finish in the fourth minute – the earliest goal by any Macarthur player in the A-League.

The hosts were indebted to a magnificent point-blank save by Adam Federici from Rudy Gestede that preserved their lead, an advantage that was doubled in the 39th minute when wing-back James Meredith headed home Jake McGing's cross to crown a fine team move.

Elvis Kamsoba reduced the deficit for second-bottom Victory after substitute Lleyton Brooks sprung the offside trap and his shot came back off the post.

But Derbyshire was played in by Michael Ruhs to coolly slot home his 13th goal of the season, strengthening Macarthur's grip on a finals berth and moving it nine points behind runaway leader Melbourne City.
