Reigning Guernsey champions St Martin's have sacked boss Alfie Le Page following 'an incident'.
Saints have refused to comment on the circumstances surrounding Le Page's sacking, and captain Matt Warren and Ben Coulter have been put in temporary charge.
Club secretary Graham Skuse says they may struggle to find a replacement for the Blanche Pierre Lane club.
"One of the problems is that it's going to be big boots to fill," Skuse said.
"They had an excellent coach up there last year and St Martin's had an excellent season only failing to win the FA Cup," he added to BBC Guernsey.
Former first team coach Colin Fallaize is now Tony Vance's number two at Guernsey FC.
