"Thorpie" tips the Bulldogs to knock off the Cats in the blockbuster on Saturday night.

Marngrook Footy Show panel member Alan Thorpe can't wait for the finals-like blockbuster between the Western Bulldogs and Geelong at Etihad Stadium on Saturday night.

"It's going to be a cracker," he said.

"Thorpie" is predicting a win forthe Bulldogs, especially if Daniel Giansiracusa can continue his terrific recent form.

"He's been fantastic. He had 30 possessions in the wet in the win over Adelaide (At AAMI Stadium) and kicked five goals in a big win in the previous round," he said.

"Thorpie" also praised the form of first-year one-time rookie-listed midfielder Brodie Moles as well as the "leg speed" of veteran Nathan Eagleton in the gutsy win over the Crows.

He described Paul Chapman as an X Factor for the Cats.

The pressure is on the reigning premier after a poor performance against Collingwood at the MCG last Saturday night.

Marngrook Footy Show host Grant Hansen focused on Geelong's lack of pace against the Magpies.

"They look like they're off the boil," he said.

Grant is tipping his beloved Bulldogs.

Gilbert McAdam and Ronnie Burns are tipping the Cats to bounce back.

But "Gilly" had a word of warning for Geelong coach Mark Thompson when it comes to the forward-line.

"I reckon he's got to make a choice ... Podsiadly or Mooney,"

Special guest and Footscray star winger/half-back flanker Stephen Power of the late 1960s and '70s paid tribute to the depth of Rodney Eade's squad.

"We've got four good outs, but we've got four good ins,"

The Bulldogs bring back Callan Ward, Robert Murphy, Shaun Higgins and Will Minson.

"They're good replacements," Power said.

Power is manager of the Taylors Lakes Family Hotel and Motel.
