Having set a new competition benchmark for tackling and pressure in last Friday night's sensational 86-point win over Geelong, the challenge now for Collingwood is to keep building on it, according to defender Heath Shaw.

Speaking before the club's recovery session at the St Kilda Sea Baths on Tuesday morning, Shaw said the Magpies have drawn enormous confidence from becoming the first team, not just to defeat the reigning premiers in 2008, but to thump them - and they now believe that anything's possible.

Shaw said Collingwood took a step forward against St Kilda the previous week, but aimed to lift the tempo and intensity for four quarters against Geelong.

The Pies achieved that, and more, with a 96-54 tackle count that literally pounded the Cats into submission.

"Our tackling and our pressure was really good and that's what we talked about before the game - we wanted to put pressure on them and force them into mistakes," said Shaw.

"They like to run the ball from the backline and our forwards put pressure on their … run and carry which made it easy for our backmen."

"Kicks were coming in high and coming in under pressure rather than that free-flowing run that they get."

Shaw said the mood around the club was extremely positive, and it's important to maintain the momentum.

"We do take confidence in the way we went about things and if we can continue that on and take that into the next four or five weeks and continue to build from that the anything's possible," Shaw said.

"We set the standard with our tackling and our pressure and if we can continue on that form then anything's possible."

"It might be a benchmark for us, but if we can improve on that and build momentum from that game that would be a good thing."

"We expect to play finals; that's what we want to do, but you have to have wins on the board to play finals," he said.

Shaw believes the Pies will go into Saturday's clash with West Coast with plenty of positives from their last meeting, the 2007 Second Semi-Final which Collingwood won in extra time at Subiaco, a match Shaw rates as one of the highlights of his career.

This time around, however, the scenario and personnel are very different, though he agrees the Eagles must not be taken lightly after upsetting the Crows at Subiaco last Saturday to bring up just their second win for the season.

"There's a few guys that are new and I suppose that we'll have to do our homework throughout the week and have a good look at those players because they obviously played pretty well on the weekend," Shaw said.
