Melbourne City, who had already booked their spot in the quarter-finals after two consecutive wins, took the lead in the fourth minute when Mariana Speckmaier broke free from her marker to receive Tyla-Jay Vlajnic’s cross from a free-kick before striking a low shot past Kaya keeper Beza Palacios.

Kaya threatened moments later with Cisneros Avila releasing Camille Rodriguez on the right but the midfielder’s hurried attempt from an acute angle hit the side netting.

Another lapse in concentration enabled Melbourne to double their lead three minutes later after Anicka Castaneda deflected Rhianna Pollicina’s corner into the path of Rebekah Stott, who finished with aplomb on the volley.

Kaya were left chasing shadows in the 10th minute as Melbourne attacked in numbers, Speckmaier turning provider when she beat the offside trap on the right to set up Lourdes Bosch to slot the ball home at the near post.

With Melbourne in the ascendancy, there was little room for Kaya on the break as the Australian side netted their fourth in the 38th minute after Taylor Otto nodded on off a corner for Bosch to head past Palacios.

Kaya, with a mountain to climb in the second half, took the initiative to put Melbourne under pressure with Dionesa Tolentin threatening in the 47th minute but her attempt from inside the box was blocked.

The Philippines side came close to reducing the deficit eight minutes later through Rodriguez, who collected Long’s pass before muscling her way into the box, only to see her shot curve away from the left post.
