FFA Cup holders Melbourne Victory have needed a lone strike from goal king Besart Berisha to see off semi-professional side Hume City and advance to the quarter-finals.
Victory were pushed to the limit on Wednesday night in an at-times feisty affair at ABD Stadium in Melbourne's northern suburbs, in a repeat of last season's semi-final.
Berisha netted from the penalty spot midway through the first half to extend his FFA Cup goalscoring record to 10 in as many matches.
Victory were fortunate to be awarded the penalty as midfielder Fahid Ben Khalfallah went to ground easily after dribbling into the penalty area.
Melbourne dominated possession with Socceroo midfield pair Oliver Bozanic and new signing James Troisi looking sharp, but Hume created several half-chances of their own.
Kym Harris was denied a second-half equaliser for Hume after some desperate, last-gasp defending from Victory.
One-time Socceroo midfielder Carl Valeri, who missed much of last season through illness, didn't take the field and is set for a stint on the sidelines after having his tonsils removed.
Tim Cahill's homecoming began in winning fashion as Melbourne City claimed a hard-fought 2-1 comeback win over former National Soccer League champions Brisbane Strikers.
Socceroo star Cahill enjoyed close to a half-hour cameo, but it was last season's A-League top-scorer Bruno Fornaroli who was the difference after netting penalties in each half.
Canberra Olympic ended the run of giantkillers Redlands United, the Brisbane-based side who shocked Adelaide United in the previous round.
Futsal international Angelo Konstantinou and prolific veteran striker Robbie Cattanach scored in a 2-0 win in the nation's capital.
Blacktown City are also through to the quarter-finals after easing to a comfortable 3-0 over fellow Sydney club Bonnyrigg White Eagles.
