Central Coast Mariners are through to the last four of the FFA Cup and NPL Victoria club Hume City can only wonder what might have been after the A-League side scrambled home through a stoppage time goal to win their FFA Cup quarter final 1-0 on Tuesday night.

Hume's misery could be compounded after fans hurled bottles and cans on to the pitch following their narrow loss.

The NPL club will be in hot water with FFA after the incident, which came seconds after full time.

Extra time and perhaps a penalty shoot out looked certain before Mariner Abraham Majok poked the ball home from a goalmouth scramble after Hume had failed to deal with a late Central Coast free kick.

Some angry fans then vented their frustration by throwing bottles and cans, while others, aware of the repuational and financial damage that might ensue from an FFA fine, implored them to stop.
