Matthew Kemp says Victory would like to be keeping more clean sheets but admits the constantly changing personnel this season has made life difficult.

Not only have Melbourne brought in a new goalkeeper this season with Glen Moss replacing the departed Michael Theoklitos but both Vargas and veteran skipper Kevin Muscat have missed games through injury while Adrian Leijer has only returned to the club recently after a stint at English club Fulham.

"We have made some silly errors," Kemp said of Melbourne's defensive record this season.

"I'm not sure if it's because of the inconsistency of the personnel there or not but it's something we are working on and as defenders we would like to keep a lot more clean sheets and we will start doing that this weekend hopefully."

While the loss of  Surat Sukha is a blow, Kemp is looking forward to the return of the dependable Vargas.

"Rody looked good (at training) so I would imagine he would be out there playing," Kemp said following the club's training session at Monash University.

"It's always good to have guys like Rody in the team because we missed him when he was out last week, so to slot him straight back in will be good for the defence.

"It was a bit strange not to have him out there last week after he had played 44 games in a row and we copped one (a goal against) but otherwise we defended quite well."

But while Melbourne's defence may not have been as watertight as previous seasons, the defenders are doing their bit on the scoresheet, with Leijer scoring the clinching goal in last week's 3-1 win over Adelaide as well as the winner in the recent 2-1 win against Brisbane.

Their efforts have contributed to Melbourne enjoying five wins from the past six matches, although the club fluffed their lines with a disappointing 3-0 loss to Sydney at Etihad Stadium in round 11.

"It's good that we have got players all around the park that can score," Kemp said.

"We are not relying on just one or two players to score goals and if you can get a couple from midfield and a couple from your defenders too, then it eases the pressure on the strikers a bit.

"It doesn't matter where we are on the park because we are all expected to score when we get our chances."
