Melbourne Victory trialled a modified midfield system in their behind-closed-doors friendly against Central Coast with new signing Oliver Bozanic playing a more advanced role.

With Socceroo coach Ange Postecoglou watching on, Victory deployed Bozanic in a more advanced role as a second attacking midfielder alongside Gui Finkler in Monday's hitout.

It left Carl Valeri in the holding role as the third midfielder in Monday’s 3-0 win over the Mariners at AAMI Park.

It mirrors the current Socceroo formation with Jedinak or Milligan at the base behind two more forward 8s (such as Rogic, Mooy or Luongo) in a 4-3-3 formation.

Victory coach Kevin Muscat was reportedly happy with the experiment and his new signing.

“He [Bozanic] gives us a different dimension without doubt, and we’re still working him through some fitness stuff to get him up to speed as quick as we can,’’ Muscat told the Herald Sun.

“He [Bozanic] likes to get forward… but it does give us another option depending on how the game’s going, what the score is at a particular time. He’s a fit boy and he gives us a different dimension because he wants to get into that final third.

“It actually created a lot more space for Gui.”

Bozanic played for 62 minutes. Besart Berisha scored twice and Daniel Giorgievski grabbed a third in a 10-minute second half blitz.

Victory face Adelaide United next week in the Westfield FFA Cup quarter final at AAMI Park.
