Senior Coach Justin Longmuir expects Fremantle to be significantly more competitive against the Western Bulldogs this Saturday at Marvel Stadium after a disappointing showing against the Dogs in round six.

The battle on the inside shapes as critical after the Bulldogs taught the Dockers onballers a lesson.

Rather than target one of the Bulldogs' stars, Longmuir said Freo would need to confront them as a collective after losing the contested ball (154-129) and inside 50s (60-45) last time.  

"As a team, we didn't play well against them last time and we got some things wrong that we need to get right," Longmuir said. 

"I strongly believe we're better than that performance, and we need to improve on what we did last week as well. We're looking forward to the challenge. 

"When we play our best footy we're connected across all our lines, which I didn't think we were last time."

Adam Treloar, Marcus Bontempelli, Tom Liberatore and Jack Macrae were all outstanding the last time Fremantle met the Bulldogs, combining for 33 clearances and getting the ball outside the contest and into dangerous positions rapidly. 

Star Freo Docker Caleb Serong (35 disposals and 10 clearances) flew the flag for his team, however, and has continued his excellent form, with the fourth-year gun shaping as a crucial player on Saturday.  

"He's a pro. He's probably been unable to train as much as he would have liked with that leg injury he's been carrying, but he mentally prepares well for games, and once he gets out there he makes no excuses for his performance and just gets to work," Longmuir said. 

"His game last week was superb. He played a bit on (Darcy) Parish at stoppage and was able to negate him, and then had 12 score involvements and 10 clearances. 

"He's continually working to evolve his game, but it's at a really high level already."

Longmuir wasn't drawn on whether Serong's season, which has seen him average 30.6 disposals and rank No.4 in the AFL for clearances, put him in line for maiden All-Australian honours. 

"That's for others to decide. He's been our best midfielder and our most consistent player across the season," the coach said. 

"There's so many midfielders and good midfielders across the comp, I don't really sit there and rank him against other midfielders.

"If that washes out at the end of the year, it would be well deserved. But I'm sure he'd rather team success over individual success anyway."

On Rory Lobb, who created a distraction for his former teammates in round six, Longmuir simply said the team would "treat him as one of 23 players". 

The coach said he would not read into the skewed results so far this season for teams coming off the bye, with the Bulldogs looking to buck the trend after their week off.
