GREATER Western Sydney has been dealt another major blow with exciting forward Cam McCarthy requesting a trade from the club.

In the same week midfielder Adam Treloar walked out on the Giants, 20-year-old McCarthy has asked for a move home to Western Australia for family reasons. 

As revealed on Channel Nine, Fremantle is leading the race to secure the forward, who was instrumental in the Giants' 7-3 start to 2015.

In his second AFL season, McCarthy finished with 35 goals from 20 games, including 29 from his first 12, a dominant sidekick to All Australian Jeremy Cameron.

Tied to the Giants until the end of 2017, it could be the second contracted player the club loses in successive seasons after Tom Boyd was traded to the Western Bulldogs last year. 

After missing out on Jack Riewoldt, Harry Taylor and Travis Cloke in recent seasons, Fremantle has its sights set on the youngster who could pair with Matthew Pavlich in a rejuvenated forward line.

When asked by Channel Nine, McCarthy's manager Colin Young confirmed the 193cm forward had requested a move back to his home state.

However, the Giants quickly denied McCarthy had requested a trade via Twitter.

"Despite media speculation, the Giants can confirm @CamMcCarthy4 has not requested a trade and is under contract until the end of 2017," the club said.
