Ferguson has instructed his players to shut up shop for the first 60 minutes of tonight's match with Perth Glory at Dairy Farmers Stadium.

Ferguson has also named an extended squad as he wrestles with possible changes to personnel after last week's loss to Sydney FC.

"We're having a look at a couple of formations and because of the amount of goals we've lost in the last couple of weeks I think we need to shut up shop probably for the first 60 minutes and we'll see how it goes from there," Ferguson said.

"It's not being negative it's more we have to be more structured and make it difficult for teams rather than giving them the simple goals we have been.

"We're not shutting down attack, we're just going to make it difficult for them. First and foremost we've got to get the structure right and get our shape right.

"That's not saying I'm going to go all negative and get everybody behind the ball. What we're trying to do is maybe cut counter-attacks and hopefully we can hit with pace.

 "You've got hopefully Williams on one side and maybe Brockie on the other just using their pace and strength and hopefully we'll have somebody in the midfield supporting going on and hopefully our fullbacks."

Fury will be hoping to reproduce the form they showed the last time they played Perth for a 2-1 win thanks to a cheeky Robbie Fowler free kick and a smashing strike from Dyron Daal.

Ferguson expects Perth to cause more than a few problems for his outfit and doesn't take too much comfort from the exclusions of strikers Branko Jelic and Eugene Dadi by Glory coach Dave Mitchell.

The Fury coach believes he has enough on his plate without thinking too much about how Perth will adjust their game plan.

"I've got my own problems. I don't want to look at Perth's problems," Ferguson added.

"They'll put a team out and we'll look at that team and we've got to try and fix it how we can go ahead and how we can go forward and how we cause them problems."
