Collingwood's promising start to the season has been boosted further with the key signing of star young forward Jamie Elliott.

Elliott, who was due to fall out of contract at the end of this season, has signed a three-year extension that will take him through until the end of 2018.

The new deal was agreed on early on Monday morning.

"I couldn't see myself anywhere else," Elliott said. 

"It's basically my second family and I hold it really close to my heart … I just love it here," he said.

"When I first came here I was shy country kid and didn't really come out of myself, but now I am just so comfortable with where I'm at and playing footy how I used to play it." 

The 22-year-old has kicked nine goals this season and has been a key part of the Magpies' 4-1 start to the year.

"We've stuck to how Bucks wants us to play and if we continue to do that and continue to bring pressure to the game and fix up and tidy up a couple of things we're hopefully going to have a really good crack this year," Elliott said.

Collingwood President Eddie McGuire said there was a reason why Elliott had become so popular with the fans: "He plays the game the way we all wish we used to play it."

Elliott, from Euroa in north-east Victoria, has played 57 games in three seasons on Collingwood's list after being on-traded from Greater Western Sydney, along with Martin Clarke, in exchange for the Pies' No. 25 pick in the 2011 National Draft.

The Magpies also announced it had signed another sponsor with La Trobe Financial signing on as a major sponsor with the club for three years.
