Skipper Phil Neville has reassured Everton fans that he and his team-mates are determined to bounce back from an 'unacceptable' performance against Arsenal.
The Toffees opened their season with a 6-1 home drubbing at the hands of the Gunners on Saturday.
But speaking ahead of Thursday's Europa League qualifier against Czech outfit Sigma Olomouc at Goodison Park, Neville has promised the fans a much-improved display.
"That is not the Everton that has shown such consistency over the last five years," he declared.
"We have been built on solid foundations and pride ourselves in being difficult to beat.
"That has been our strength. Even if the quality of our play has not been good at times in the past, people know that we are hard to beat.
"We need to toughen up and get back to basics. I know we are hurting and we have got to take responsibility for that performance.
"It is not acceptable and, believe me, the players will not accept it. You talk about our famous spirit, well we have got to show it now. This is a time for strong characters.
"We have got to show everything that has made us the fifth best team in England (last season). This is a big test for us."
