Furious boss Carlo Ancelotti rounded on his Everton flops after they slumped to a limp defeat at Wolves.
Raul Jimenez's penalty and second-half goals from Leander Dendoncker and Diogo Jota earned a comfortable 3-0 victory for the hosts.
The Toffees remain 11th in the Premier League having won two of their last nine games and with little hope of making a late push for Europe.
An exasperated Ancelotti said: "It was a really frustrating day and performance. The spirit of the team was unacceptable.
"There are some excuses but I don't want to have excuses, the performance was not acceptable. I spoke to the players and we have to prepare and work differently and have a different attitude.
"I don't want to talk individually about every single player. I said to them this attitude is not acceptable for me and we have to change immediately. I want to see a different spirit.
"If I have to be honest, in some games the spirit was really good. Liverpool, Norwich, Leicester. It's difficult to accept for this reason because this team has a fighting spirit."
Wolves rose to sixth to keep their fading Champions League hopes alive with three games left.
Boss Nuno Espirito Santo has less than a year left on his current contract and denied reports he was close to signing a new deal.
He said: "It's not true, I still have one more year of contract. I have seen the stories."
