WESTERN Bulldogs coach Luke Beveridge is hoping his side can maintain its winning momentum and stay in the mix for a top-six finish, describing winning a premiership from a wildcard spot as a "monumental challenge".

The Bulldogs sit eighth (with a game less played than seventh-placed Collingwood) heading into their Round 20 clash against Richmond at Marvel Stadium on Saturday night.

They are only four points off fourth-placed Brisbane on a congested ladder, so avoiding the first-week play-off is still a firm possibility. 

The Dogs famously won the 2016 flag after finishing seventh and winning four consecutive finals.

"If you finish seven to 10, you've got to win five in a row, and we know how hard it is to win four in a row," Beveridge said on Friday.

"Everyone's doing their best to try and climb into that six as winning five in a row is going to be a monumental challenge.

"Ultimately, as we know, top four, definitely top two, is the absolute objective for anyone, but it's going to be hard for the wildcard teams (to win a flag)."

The Bulldogs have won their last two matches and welcome veteran Tom Liberatore back after missing last week with general soreness.

They will start raging favourites against the last-placed Tigers but Beveridge was adamant his team is not assuming a walk in the park.

"I know they're (Richmond) obviously quite low on the ladder, but in terms of the threats they can offer to you, well you only have to look at recent history with the Giants beating the top side in Fremantle, went on to beat Geelong and then were beaten by at the time the bottom side in the Bombers," Beveridge said.

"It's obviously a reminder to the competition that it doesn't matter who you play, if you're not right on your mettle you can be compromised and they can get you on the day."

"So we'll approach the Richmond game accordingly and we won't take them lightly."
