CARLTON needs to bring its highest intensity to reverse a poor recent record against Greater Western Sydney, says star midfielder Bryce Gibbs.

The Blues have lost by 81 and 78 points in their last two games against the Giants and will look to improve their recent record on Saturday at Spotless Stadium.

It looms as a crucial contest for both teams, with Carlton needing a victory to keep its finals hopes alive, while a GWS win could push Leon Cameron's men into the top four.

"We've got a tough game ahead of us. Our form hasn't been great the last couple of weeks," Gibbs said at the club on Tuesday.

"We've played some really good footy against quality opposition this year. It's not an easy task travelling to Sydney and playing them on their deck. It basically comes down to our pressure and effort.

"If you're 5-10 per cent off in that, you're going to cop a whack." 

Gibbs, 27, is preparing to line up in his 200th match against the Giants. He was drafted at No.1 in 2006 and has proven a remarkably durable player, with 2015 the only season he has managed fewer than 21 games.

Leading into that season, he had missed only five of his past 182 possible games. Injuries to his back and pectoral muscle, as well as a two-week ban for a driving tackle on Port Adelaide's Robbie Gray, curtailed the season that followed his best and fairest campaign in 2014.

"I've had ups and downs in my career, in terms of form, but I think the older I've gotten, the more responsibility I've had on me leadership-wise," he said.

"It's funny, you come in as a young kid and you're living your dream and you can get pretty content just playing footy and sort of going through the motions at times.

"It's probably now that I'm starting to get a bit older, realising that I'm probably more at the end of my career than at the start, that you need to start really knuckling down and making every day count."

The South Australian native signed a five-year deal with the club in 2014 and said he never gave much consideration to leaving the Blues.

"It was difficult but I was pretty clear in my mind early on that I didn't want to leave," he said.

"I would've been naive if I didn't have a look to see what was out there. There were a couple of initial conversations that happened but they didn't get too far.

"I was pretty set in my mind that I wanted to stay at Carlton."
