Everton supporters will stage a protest against owner Farhad Moshiri on Saturday as frustration grows over the club's current direction.
The 27 Campaign have been vocal throughout the summer about their wishes for Moshiri and Bill Kenwright to leave the club, over what they percieve to be mismanagement at the top level.
Everton came perilously close to relegation from the Premier League for the first time last season, avoiding the drop with just one game to spare after a 3-2 victory over Crystal Palace on May 19.
The summer break has done little to ease tensions however, with top scorer Richarlison sold to Premier League rivals Tottenham, and no sign of a replacement arriving.
And issues have been further exacerbated by performances on the pitch, with Frank Lampard's men soundly beaten 4-0 by MLS outfit Minnesota United on Wednesday.
Announcing the reasons for the action, The 27 Campaign cited a continual lack of communication and engagement from the board.
'The 27 Campaign believe that the current leadership of Everton including the Chairman, board and executive, fall well below the requirements of a modern football club, in terms of skills, commercial experience, governance and ambition,' they wrote in a statement.
'This conclusion is evidenced by the complete mismanagement of footballing operations (only now being addressed through Kevin Thelwell, Frank Lampard and his team), the financial performance of the club (leading to record losses & significant restrictions on current and future transfer activities) and concerns over the future ownership and funding of the club including Bramley-Moore stadium.
'More timely, with only two weeks to the start of the season, the club finds itself struggling in the transfer market, having sold its key playing asset in Richarlison and no indications of the squad strengthening desperately needed by the manager and fans.
'Recent responses issued by the club on behalf of Farhad Moshiri have failed to allay concerns. They do not represent engagement and show no evidence of him listening to the concerns of many fans.'
Everton have made just one signing this summer, with out of contract centre back James Tarkowski arriving from Burnley.
The Toffees have been linked with the likes of Jesse Lingard and Maxwel Cornet, but have yet to finalise any deals for an attacker following the departure of Richarlison.
