THE WESTERN Bulldogs have suffered another blow days out from its Grand Final defeat with emerging midfielder Pat Lipinski requesting a trade to Collingwood.

As revealed by AFL.com.au, Lipinski has been offered a three-year contract extension by the Bulldogs, but has informed the Dogs he wants to head to the Pies.

The decision has infuriated the Bulldogs.

"The club's preference is to retain Pat as a Bulldogs player into the future, and it tabled a three-year contract extension earlier this season as a show of faith in the talented 23-year-old," the Bulldogs said in a statement.

The Bulldogs will now work through a deal with Collingwood when the Continental Tyres AFL Trade Period opens on Monday October 4.

Collingwood currently holds picks 36, 39, 41, and 45 in the 2021 NAB AFL Draft.

The problem facing the Pies is that it needs to stockpile draft picks to match a bid for father-son draft prospect - and most likely this year's No.1 - Nick Daicos.

Collingwood also has lingering salary-cap issues that resulted in the bitter fire sale of Adam Treloar, Jaidyn Stephenson, and Tom Phillips during last year's Trade Period.
