Kevin Muscat will aim to maintain his unbeaten coaching record against Adelaide United on Saturday when Melbourne Victory host their arch-rivals as the reigning Hyundai A-League champions seek to become even more ruthless.
The Big V have won their past five games in all competitions and will move top of the A-League if they defeat Adelaide - at least until Brisbane Roar play on Sunday - but Muscat is still targeting "perfection".
Clearly last week's second half against Central Coast Mariners, where Victory failed to extend their lead and eventually conceded for a nervous finale to their 2-1 win, did not impress the former Socceroos defender.
With Besart Berisha, Carl Valeri and Jason Geria all in line for recalls this week, Muscat has challenged his side to keep their foot on the opposition's throat when in winning positions.
"There's one glaring thing for us that we've got to control games for longer, and it's a big ask because in a competition that is so even every team is going to get an opportunity in a game where they get on top," Muscat told reporters on Friday.
"When the opposition does get their moments, we've managed to defend very, very well this season but trying to stay in control for longer; we want to be a lot more ruthless in our transition.
"We want to defend better - we weren't pleased with the goal we conceded last week."
Muscat will be looking to maintain his unbeaten coaching record against United on Saturday.
Since Muscat took over from Ange Postecoglou as Victory's boss, the former captain of the Big V has earned four wins and three draws in competitive fixtures against the Reds.
Muscat also relished playing Adelaide as a player - the two A-League grand final triumphs were particular highlights - and the 42-year-old admits this clash is special.
"We've actually managed to play Adelaide in a lot of meaningful games over the 11 years, so there is a little bit of feeling from that perspective," he added.
