PREMIERSHIP Western Bulldogs midfielder Tom Liberatore has re-signed for a further two years.

Originally due to come out of contract at season's end, he is now locked in until the end of 2021.

Liberatore, 27, was an integral part of the 2016 flag side and is among the heart-and-soul players at the Bulldogs.

Having endured two knee reconstructions throughout a career that has included the 2014 best and fairest, Liberatore is a fan favourite.

Taken as a father-son selection in 2010, Liberatore has lined up in 128 career matches and is keen to see that run extend.

"Being loyal to my teammates is a big thing for me," Liberatore told westernbulldogs.com.au.

"I've been part of this group for nine years now and I'm happy where I am.

"It's been good to come back from injury and play every game so far this year, and nice to sign on for two more years to have that comfort around the future.

"I'm really looking forward to the back half of the year and how we can grow this year, and over the next couple of years.

"This group has the promise and the talent to get back to the top, and we've shown that ability in certain games this year. I think that we will keep getting better."

Liberatore is averaging 23 disposals per game this season and is ranked No.18 in the competition for clearances per game.

However, Dogs list manager Sam Power said Liberatore's influence couldn't be measured in stats alone.

"We're obviously rapt to have Tom sign on for two more years," Power said.

"He is an important player for our football club with the way he plays, as he has shown throughout the first half of this year in his return from a second ACL reconstruction.

"Tom is the type of player who makes his teammates walk taller. 

"His selfless approach to the game makes those around him better players, and we know he is driven to help this group taste success in the years to come."
