Sean Dyche says he is working harder than he ever has as a manager to turn around Everton's gloomy season.
The Toffees have won just twice in this Premier League campaign and sat two points above the relegation zone in 15th heading into the midweek programme.
The Merseysiders face fellow strugglers Wolves on Wednesday and will be looking for their first win in six games, having failed to score in their last four.
"Sometimes me, my staff and the players haven't delivered as well as we could do," said Dyche, whose managerial career began at Watford in 2011 before a 10-year spell at Burnley.
"But we work tirelessly. This is the most work I've done in all my years in management, at this club, without a shadow of a doubt.
"I'm more than ready for the challenge. It could be easier because for sure I've made errors this season, the team has made errors, they are there for all to see.
"It's a fact of life as a manager, you have to get the margins right and we haven't done so far this season.
"You've got to win games and we haven't won enough games."
Dyche succeeded Frank Lampard in January 2023 with Everton in the relegation zone, but they secured safety with a win over Bournemouth on the final day of the season.
He then guided the Toffees to a 15th-place finish last season despite the club being deducted eight points for two breaches of Premier League financial rules.
"Last season we were on six points [after the first points deduction] at this stage, we are on 11 now. By no means was that where I was expecting to be," added Dyche, whose contract expires at the end of the season.
"We've got ourselves in a position where we feel we should be doing better - myself included - and now it is about taking on the challenge.
"I'm still trying to crack the code, as others have done before me."
