There was never any realistic expectation that a deal could be completed mid-season, but the sheer volume of discussion surrounding the rumour made it difficult to dismiss completely.
Where there is so much noise, there is often some truth.
Chelsea would prefer that not to be the case. The club moved quickly to shut down any suggestion of Palmer leaving, briefing that there is no possibility of a transfer.
Yet those messages have not been universally accepted across the football industry, with Flashscore sources believing this is a strand of gossip worth closer examination.
It can be true that Chelsea have no desire to sell Palmer, while also being true that Manchester United are beginning to form a long-term vision of what might be possible.
From United’s perspective, Palmer would be a good fit. He offers the type of creative focal point the club will desire beyond Bruno Fernandes, while also ticking several key boxes in that he has Premier League experience, homegrown status, commercial appeal and an ideal age profile for a rebuilding side.
There is also a personal connection as Palmer knows United sporting director Jason Wilcox from their time together at Manchester City.
United’s wider recruitment strategy places an emphasis on players proven in the Premier League, and Palmer returning to his home city as part of a long-term rebuild is a scenario that clearly appeals at Old Trafford.
But why is the rumour circling now?
There have been frustrations at Chelsea around Palmer’s fitness and conditioning this season, and his form has not consistently reflected his true ability or potential.
That has coincided with an unsettled period behind the scenes, with the club moving from Enzo Maresca to Liam Rosenior as head coach.
Palmer’s body language and overall demeanour have occasionally hinted at a player not entirely at ease, prompting suggestions that he may be feeling unsettled in London and missing life in Manchester, where he grew up.
Images from his childhood showing Palmer as a Manchester United supporter have resurfaced online, while his relationship with Wilcox further connects the dots at a time when United are beginning to think about their next phase of growth.
Sources accept there is a genuine possibility Palmer could one day play for United - but the uncertainty lies in when that will happen.
Chelsea will continue to insist he is not for sale and there is no indication that stance will change in the short term.
But modern football is fluid and situations can change quickly. As such, the idea of Palmer eventually moving to Old Trafford is one that should continue to be viewed with an open mind.
Whenever Bruno Fernandes moves on, United will require a replacement, and Palmer is likely to be near the very top of their shortlist.
