Carlton have expressed interest in obtaining the star’s services, with now Essendon and Hawthorn joining the battle.
Shiel, 25, last month declared he will see out his contract at GWS, which keeps him in orange until the end of the 2019 season, but it hasn’t stopped clubs trying to secure him a year early.
According to The Australian, GWS might need to offload one of their better paid players this year for some salary cap relief, with bottom-placed Carlton identifying Shiel as a high priority target.
Carlton have been the least successful team from the original 16 teams, having just won three games from their past 30, meaning they’ll need to do a lot of convincing their rebuild is worth Shiel’s signature.
Last month, Shiel revealed to Triple M he has no plans to part-take in the trade period beginning on October 8.
“Unless the Giants are exploring flicking me at the end of the year, at this stage I’m pretty happy up here and I’m contracted until the end of next year,” Shiel said.
“I’m enjoying my time here and I certainly haven’t looked at any options to leave at the end of this year.
“I’m pretty settled in Sydney with my partner, Georgie.”
Worsfold said Essendon will be pretty active in the trade period.
“We’ve certainly identified if we were to go into trade what we’d be looking for,” Worsfold said.
“(List manager) Adrian Dodoro is doing a huge amount of work presenting to the list management committee around the potential availability of players who would fit the need we might look for in a trade specifically.”
Hawthorn will throw their hat in the ring for Shiel if their bid for West Coast’s Andrew Gaff goes sideways, as the midfielder has reportedly been offered a $1.2 million dollar contract at North Melbourne.
If Gaff accepts North’s offer or opts to stay at West Coast, Hawthorn will bid hard for Shiel after gaining some extra money thanks to the retirement of great Cyril Rioli.
Shiel has played 131 games for the Giants, only missing one game in two years, and Carlton believe he is the perfect fit for their list.
