WEST COAST captain Darren Glass isn't giving away any of his defensive secrets ahead of a likely clash with Fremantle star Matthew Pavlich in Saturday's Western Derby.
 
Hawthorn spearhead Lance Franklin is the latest feather in Glass' cap after the skipper kept him to just two goals and four marks in West Coast's round five loss. 
 
But Pavlich, after hitting some imposing form of his own in round five, looms as the key challenge for West Coast as it tries to overturn a woeful recent record in derbies.
 
"I think he played a very good game on the weekend. He played up the ground and deep as well. So there's no doubt at some stage I'll match up on him," Glass said from Subiaco Oval on Tuesday.
 
"He's a very difficult player to match up. He's got so many strengths, he can take the ball in the air, on the ground (and) he's certainly a long, penetrating kick.
 
"I'll enjoy matching up on him, I'll enjoy the challenge. I've had mixed results on him in the past, so I look forward to that challenge if and when it comes."
 
Glass said the skipper wasn't West Coast's only concern in a Freo side that has won five of the last six derbies and is fresh off its first win of 2009.
 
"No doubt he's a very important player to them, but there's certainly more weapons to Fremantle than just Matthew Pavlich," Glass said.
 
"That was the strength of their game on the weekend, that they had contributors all over the ground.
 
"Our focus is about shutting Fremantle down. Pavlich is an important part, but he's not the only part."

Glass said West Coast's recent record against Freo stung and the side was determined to address it this season.

He also fired a veiled derby week barb, noting Fremantle's habit of lifting for the cross-town grudge matches. 

"It seems to be that they play their best footy in the derby," he said.

"No doubt that we want to certainly play our best footy each and every week – we want to be consistently good week-in week-out.

"That's going to be the same this Saturday."

Asked why Fremantle plays its best football against the Eagles, Glass said: "You'd have to ask them that. I guess they'd want to know why they play well in derbies as well.

"They just seem to have played well in derbies. They seem to have had a good record of late. I think it's just reflected in the results I guess."

But while he was ruthless in pursuit of the win this week, Glass said he felt for young Fremantle midfielder Rhys Palmer, who has been ruled out for 12 months after tearing his anterior cruciate ligament.

"It's disappointing to see such a young player, and developing well, to see him go down," Glass said.

"Certainly I wish Rhys all the best with his recovery."
