Mitchell is keeping his selection cards close to his chest ahead of Saturday's match against at Etihad Stadium.

With the club's leading goalscorer Branko Jelic returning from injury and new signings McGarry and  McBreen all available, Mitchell says he's not sure who'll line up for Glory.

"I haven't decided who will play yet," Mitchell said.

Mitchell has started with the same XI in the last two home games against Newcastle and Sydney FC but he's happy to have a selection dilemma.

"The good thing is when you bolster your squad, its competition for places which can only be positive," he said.

Dutch star Viktor Sikora and Wayne Srhoj have both travelled with the squad but the duo will not be considered for Saturday's clash, though the pair could be available for Tuesday's match with Adelaide at Hindmarsh Stadium.

It's a tough week for Glory with three games in six days.

"It will certainly test our squad," said the coach. Experienced defender Chris Coyne will re-join his team mates in Melbourne after spending the week in China.

Coyne is hoping to secure a contract with Super League club Shandong Luneng ahead of the World Cup.

"He's used to flying and he'll be part of our squad for the game. He's a hard nut and he's bullet proof when it comes to that," said Mitchell.

With Victory in third spot and Perth in sixth, Mitchell is cautious of a Melbourne side that have lost their last two matches.

"At home, it will be a big crowd for the Victory and I'm pretty sure they'll be up for it because they've lost second spot and they'll want to retain," added Mitchell.

"The race is on for them now, and for us it's a real important game to establish ourselves as a contender, and there is no better game than Melbourne to prove a point."
