MELBOURNE star Clayton Oliver looks unlikely to face St Kilda on Saturday night after failing to complete a crucial training session on Wednesday morning. 

Oliver has been sidelined for six weeks with hamstring issues and a nasty infected blister, and the star midfielder had been pushing for a return this weekend.

Speaking before training on Wednesday, coach Simon Goodwin was hopeful the four-time Demons best-and-fairest could finally return after numerous false starts.

"If I can be as honest as I can be, (Oliver) has got one session that he needs to get through in terms of ticking off a marker," he said.

"We're really hopeful that he gets through this (training session on Wednesday) and he'll be available to put on the Melbourne jumper on Saturday night."

But about an hour after Goodwin's press conference, Oliver left the ground at Casey Fields early after failing to complete a series of run-throughs.

Meanwhile, Goodwin says the the Dees are working harder than ever on their goalkicking in a bid to turn around the inaccuracy that threatens to derail their premiership campaign. 

After winning just two of their past five games to be eight points behind third-placed Brisbane, Melbourne is clinging on to fourth spot by percentage.

During that poor run, they have averaged just 61.4 points a game.

In Sunday's shock two-point defeat to GWS, the Demons' return was just 5.15 from 73 inside 50 entries in wild and wet conditions in Alice Springs.

The 2021 premiers' forward line has come under intense criticism, something Goodwin accepts is fair.

"We've had five weeks where we've kicked no more than eight goals so we don't live under a rock and think it's not an issue," Goodwin said on Wednesday.

"We want to be a team that scores more on the back of some of the unbelievable work we're doing defensively and in our contest work.

"At some stage, it's going to turn and we're going to start to get bang for buck.

"We've given more minutes to goalkicking than ever before in the history of our footy club."

Accuracy in modern footy is often a gripe of former star forwards, with sport science and fitness staff known to overrule frequent training in the art of goal-kicking.

But Goodwin said Melbourne's fitness group had allowed the players free reign to work their way out of the form slump.

"If you can look outside right now, and this is prior to training, we've got 30 blokes out there having shots at goal, running around poles," he said.

"Choco (Melbourne's head of development Mark Williams) is driving a really big program for us.

"Our high-performance team are very supportive of how much goal-kicking we do."

With premiership hero Bayley Fritsch out for up to eight weeks with a foot injury, Melbourne's forward set-up will look different for Saturday night's clash with St Kilda at Marvel Stadium.

Fritsch underwent surgery on Tuesday and Goodwin is hoping the 26-year-old can return around finals time.

Young key forward Jacob van Rooyen will almost certainly be back to face the Saints following his surprise axing to the VFL last weekend.

Van Rooyen responded to being dropped in style, booting four goals in Casey's VFL smashing of GWS.
