Greater Western Sydney defender Nathan Wilson has officially requested a trade home to Western Australia in the upcoming trade period due to family reasons.

Fremantle is reportedly the front runner for the 24-year-old's services.

Small forward Devon Smith and midfielder Matthew Kennedy have also informed the Giants they wish to leave the club and explore their trade options.

Carlton is reportedly in the box seat to secure Kennedy, while the Blues are also said to be interested in Smith, as are Collingwood and Geelong.

"We are sympathetic to Nathan’s situation and we understand Devon and Matt’s wish to explore opportunities during the trade period,” GWS General Manager Football Wayne Campbell said.

"We’ll now work with the respective players and their managers to arrive at the most appropriate outcome."

Meanwhile, Tendai Mzungu has announced his retirement from AFL football.

Mzungu played four games for the Giants this season, after 102 matches for the Dockers from 2011 to 2016. He was delisted by Fremantle at the end of last season, before being recruited in the Rookie Draft by GWS.
