Toby McLean and Tom Liberatore are firmly in the mix to return as the Western Bulldogs prepare for Friday night's clash with Greater Western Sydney.

Coach Luke Beveridge made five changes for round two after the long layoff, but there could be more this week.

"He (Liberatore) had a really good session on Saturday and he's come through that with flying colours," Beveridge said.

"That was the last one he needed to tick off and so we'll definitely consider him for Friday night."

Beveridge highlighted a number of areas that needed addressing in the aftermath of the round two loss to St Kilda, most notably the midfield.

The Bulldogs have conceded the second-most points of any team this year and have scored just 83 points combined across the two games. 

"There's some quite blatant things that we've identified that we can fix," Beveridge said.

"Some of those are just fundamental skill errors and decisions.

"Our midfield and our backline, our counterattack and our stuff out of stoppages hasn't been anywhere near as productive as what it was last year. 

"You have to re-establish yourself all over again and that maturity as a football team isn't quite there yet."
