KUALA LUMPUR: Last year's finalists Selangor survived an astonishing second-half collapse on Sunday to squeeze into the FA Cup semi-finals on aggregate.

At the MBPJ Stadium, Selangor booked their ticket to the final four with a 6-4 aggregate victory despite suffering a 3-2 defeat on the night against Star City.

Carrying a 4-1 cushion from their first-leg win in Kangar on Sept 19, Kim Pan Gon's Red Giants initially looked in control.

Defender Zikri Khalili headed home the opener in the ninth minute before Brazilian attacker Vitor Pernambuco doubled the advantage in the 33rd minute to put Selangor 2-0, and 6-1 ahead on aggregate.
