Ashley Williams has revealed the Everton squad will hold a meeting this week to try and get to the bottom of their dip in form.
The Toffees won five of their first six games in all competitions to climb as high as second in the table by the middle of September.
However, an EFL Cup defeat at home to Norwich has sparked an alarming slump in form that has seen the side drop down the table.
Ronald Koeman’s side have taken just six points from their previous seven games, with their most recent match a dour 1-1 draw at home to rock bottom Swansea.
The miserable run has sapped much of the optimism generated by the early weeks of Koeman’s reign and suggests the Dutchman’s rebuilding job is a lot more comprehensive than perhaps he first imagined.
Wales captain Williams was one of Koeman’s summer signings and the 31-year-old admits the team’s poor performances are becoming a concern.
“It is frustrating for all of us.
“We are trying our best but for whatever reason this [inconsistency] is happening.
“This week we will speak a bit more about that because I feel it is definitely something we need to work on in the 90 minutes and from game to game.”
Things are unlikely to get easier for the Blues with a trip to Koeman’s former club Southampton next up on Sunday before a game at home to Manchester United seven days later.
