Forest Green Rovers has accused Watford of giving 'football a bad name' by approaching their manager Rob Edwards without contacting them first.
Edwards has guided Rovers to the League Two title this season in what was his first job in the professional club game.
90min reported on Wednesday morning that the Welshman was being targeted by the Hornets and things have moved swiftly since then, with Forest Green confirming that he has left the club in an explosive statement.
"FGR confirms the departure of Head Coach Rob Edwards. Rob was a key part of the team that gained promotion to League One this season," it read.
"We’re disappointed that our support, loyalty and honesty towards Rob has been repaid in this way - with negotiations taking place behind our backs.
"We had no contact from Watford, from whom we might expect less, but in any event this kind of behaviour gives football a bad name.
"We thank Rob for all his work at FGR - forgive him the manner of his departure and wish him well."
90min understands that Edwards' arrival at Watford will be confirmed before the weekend. Roy Hodgson is currently in charge of the already-relegated Hornets, but he has already said he will be stepping back into retirement at the end of the season.
