The Premier League is on a collision course with some of its clubs after performing an apparent u-turn over dressing rooms less than three weeks before the start of the new season.
Sides had been thought that it would be business as usual when the campaign kicks off on August 14, with temporary, socially-distanced facilities a thing of the past and original home and away dressing rooms back in use.
However, sources have disclosed that the top flight has now told its clubs that dressing rooms need to again be socially-distanced, which has left many contemplating a return to banqueting suites, bars and cabins on car parks.
With fans set to be present, there are grave concerns that clubs face a logistical nightmare with some known to be in uproar over the move.
Some have already made the league aware that they have no intention of going back to last year's arrangements, while others have pointed out it would be 'impossible' to do so given the return of fans.
Some are even understood to have started dismantling facilities and have been left stunned by the volte-face.
'It's absolutely crazy,' said one official. 'There was a call between the league and all the facilities guys last week and this was not mentioned.
'Weeks ago we were told that everything would be back to normal. Some clubs have started taking down the facilities they used last season and now they're being told this? It isn't fair and it doesn't make any sense.'
Many clubs with older stadia had to make new arrangements last season. Manchester United and Everton created temporary facilities for visitors outside their grounds.
Aston Villa had the away team use the media room and at Leeds, the visiting side used a bar area and then came down steps in the stadium to the pitch. Chelsea hosted their opponents in a nearby leisure centre.
With the return of supporters, a return to such set-ups will be incredibly challenging.
understands that clubs are preparing letters to the Premier League, in which they reject the proposal.
Premier League sources say they are continuing to go through the protocols and that no decisions have been made. They add that work is ongoing an say they are working to find solutions with clubs with safety a priority at a time when numbers of cases are still high.
In June, the Premier League said that it would remain agile to the changing environment and take emergency measures if necessary.
