The future of GWS midfielder Dylan Shiel remains up in the air, with a monster offer from the Blues now on the table for the 25-year-old.

Shiel is still contracted for next season, although with Hawthorn, Essendon and Carlton looming as potential destinations, the Giants will need to consider moving him on, as they need to free up salary cap space.

The Blues' offer is the biggest, although Talking Footy's Tom Browne understands the Giants are more and more confident by the day that Shiel stays on.

If he does stay, it may mean the end for ruckman Rory Lobb, with Fremantle interested in the versatile big man.

Lobb is also contracted for 2019, but with the Giants needing to find some cap room, he could be one of their stars on the trading block.

“In recent weeks, he (Shiel) was widely tipped to return to Victoria - Hawthorn, Essendon and Carlton all chasing him pretty hard,” Browne said.

“My understanding is Giants bosses have been working hard to keep him, in fact they met with him last week. They’re increasingly confident Shiel will stay.

“In money terms I’m told Carlton has made the biggest offer, over a million dollars a season.

“The Giants need to free up salary space so Rory Lobb to Fremantle is a big possibility.”
