Perth teenager Cody Ninyette could swap places with Tendai Mzungu at Greater Western Sydney when the AFL national draft is held in November.

Perth are increasingly confident Mzungu, who has played four games for the Giants this season after overcoming a severe hamstring injury, will return to the Demons next year to see out his career.

And his likely return could be enough to persuade veteran midfielder Clint Jones to remain at the club for another season as part of its rebuilding campaign.

But 19-year-old Ninyette is not likely to be part of that rebuild after emerging on the Giants’ draft radar.

Lightning fast with hands and feet, though weighing just 62kg, Ninyette produced a strong finish to the WAFL season, including a seven-goal haul against East Perth, with most of the goals kicked on West Coast defender Jackson Nelson.

Ninyette played 18 league matches this season, averaging 15 disposals, four tackles and 1.5 goals a game, with Perth sources saying he has adapted rapidly to the demands of senior football.

The Giants took a close interest in him from the middle of the season when he bagged four goals in a win over Claremont and three against Swan Districts.

GWS gave Mzungu, 31, an AFL lifeline this year after Fremantle de-listed him following 102 games over six years.

After a bright pre-season and elevation to the senior list, Mzungu tore a hamstring so badly in the first game that he missed the next 10 matches.

He returned for three games in July, all losses. The Giants then replaced him with midfielder Stephen Coniglio as they pushed towards the finals.

Perth believe Mzungu will return to the Demons if his rookie contract is not extended by GWS.

Mzungu played 72 league matches for Perth and won the Butcher Medal as club champion in 2010 to prompt the Dockers to draft him as a 24-year-old.

He added another 23 games for Peel in 2015 and last year, including a starring role in their maiden premiership last season.
