Joe Daniher's wish to join Sydney heads a lengthy list of AFL trade negotiations ahead of the Wednesday night deadline.
Essendon have dug in their heels over the All-Australian key forward, saying the Swans will have to make an attractive offer for them to let him go.
The Bombers are after a top player and, so far, the two clubs look a long way off reaching a deal.
Essendon small forward Orazio Fantasia has already confirmed he is staying after strong speculation of seeking a trade to Port Adelaide.
As well as the Daniher impasse, Sydney's Tom Papley is one of three small forwards keen to join Carlton.
Gold Coast's Jack Martin also wants a trade and Adelaide veteran Eddie Betts is expected to return to his old club.
There's a trade log jam at St Kilda, with a number of incoming and outgoing deals yet to be finalised.
Key forward Josh Bruce wants to join the Western Bulldogs, while four-time club best and fairest Jack Steven is keen to join Geelong for personal reasons.
The Saints hinted they wanted to bring in Fremantle speedster Brad Hill, but those talks hit a major snag last week.
Port Adelaide pair Paddy Ryder and Dougal Howard and Sydney's Zak Jones also are linked to St Kilda.
The Bulldogs are eyeing Adelaide defender Alex Keath, but off-season surgery for a stress fracture has complicated that scenario.
All-Australian Tim Kelly is the biggest trade so far, with West Coast giving up a host of draft picks to bring him back to WA after two outstanding seasons at Geelong.
Trade period started last Monday and, to date, only seven players have found new homes either through deals or free agency.
