HOMESICK Melbourne key tall Kristian Jaksch will tell Greater Western Sydney he is coming home in the days after Round 23, sparking an immediate bidding war.

The Herald Sun understands the 195cm swingman has already made clear to coach Leon Cameron he wants out but will officially request a trade in his season-ending exit interview.

The imminent departure of Jaksch came as the Giants announced a two-year contract extension for Jon Patton, who was cut down by another knee injury last weekend.

The Bulldogs would have offered Patton a five-year deal but the former No. 1 pick, already locked away until 2015, is now signed until the end of 2017.

GWS list manager Steve Silvagni has had extensive conversations with his management and is aware the Giants have no hope of retaining Jaksch, who was pick 12 at the 2012 national draft.

It is another blow to the club’s batch of talls, with former No. 1 pick Jon Patton needing a second knee reconstruction after falling last weekend.

The 19-year-old is a rare commodity: a high draft pick with two years of development in him desperate to get to a Melbourne club.

He spent time at home for a family celebration earlier this month while battling an ankle injury, crystallising his intention to return home.

Carlton will be a keen suitor but the Western Bulldogs and St Kilda are also crying out for a young key forward.

Geelong and Hawthorn could also emerge as contenders, with the Hawks having form after plucking Jack Gunston from Adelaide as he was ready to hit stride.

Every Victorian club has inquired about Jaksch to his manager Matt Bain, of Stride Management, but none has emerged as the frontrunner.

GWS had offered Jaksch a new deal but is growing increasingly resigned to extracting a pick or player in exchange.

But the ability to trade him to any of the ten Victorian clubs at least maximised their chances of fair compensation.

The Giants still have 17 players who are 193cm or taller on their list, but are desperate to ensure the leakage of Victorian teens heading home does not become a torrent.
