Sydney, Collingwood and Geelong are understood to be expressing interest in the Bulldogs top draft selection ahead of this month's National Draft.

The Dogs currently first enter the count at Pick 23, with the Whitten Oval side likely to be willing to part with their first selection in order to strengthen their bid for father-son prospect Sam Darcy.

The teenage sensation is set to warrant a top three calling at the draft, requiring the Bulldogs to hand over close to 2000 draft points.

The Dogs' current hand of picks 23, 43, 44, 45, 52 and 93 tally 2148 points, with further security required should Darcy's name be called out at Pick 1.

Parting with Pick 23 for multiple later selections would aid the Dogs' planning to land Darcy, with the Magpies, Swans and Cats understood to be eyeing the Dogs' selection, per Fox Footy's Ben Waterworth.

Geelong are reportedly seen as the most likely club to land Pick 23, with the Cats having shown some desire to trade back into the earlier rounds.

Adding Pick 23 to their string of selections would see Geelong hold five second-round picks, with Picks 22, 30, 32 and 34 currently calling Kardinia Park home.

Geelong could package one of those selections with another pick, with the Cats also holding Picks 50 and 91 as well as future picks selections for 2022 that could appeal to the Bulldogs.

A deal is unlikely to fall before Monday's trade deadline for draft picks for the National Draft on November, which will commence on 24-25, with club's more liekly to have trades confirmed on draft night.

According to Waterworth's report, the Blues' second-round selection at Pick 25 is also on offer to interested suitors, while Essendon are continuing their planning to trade back into the draft, with their second earliest pick coming at 51 on the board.

A trade between Collingwood and St Kilda was lodged on Friday that saw the Saints land Pick 55, while the Magpies acquired a future fourth-round selection tried to Adelaide.
