Wimbledon manager Terry Burton has warned chairman Charles Koppel he may quit unless the club find a new home.
The Dons lost their third straight game 1-0 to Barnsley at Selhurst Park, where angry supporters protested against a proposed move to Milton Keynes.
Wimbledon have not owned their own stadium or training ground in the two years Burton has been in charge.
He has already threatened to quit once this season over the club’s uncertain future.
With one year left on his contract and the threat of losing 16 out-of-contract players this summer, he is again considering his position.
He said: ‘‘I’m in my last year here now and I’m not sure what the future holds. There are a lot of positive things at this club, but also some negative ones.’’
