Phil Jagielka has admitted he is particularly unhappy with his form this season, and the Everton defender is planning on making some big improvements in the coming weeks.
Everton are currently 13th in the Barclays Premier League table, and have collected just six points from seven matches.
The side face a tough fixture this weekend, with Chelsea at Stamford Bridge to contend with, and Jagielka has revealed that he is being particularly hard on himself in the hopes of improving.
"Am I happy with my form? No, not really," Jagielka told The Daily Mirror.
"I'd love to be standing here and saying, 'Yes, I'm really, really happy', but I analyse my own game and set pretty high standards."
Jagielka insisted that there have been problems in shoring up Everton’s defensive line up during the season, and it is an issue that the England international plans to correct as soon as possible.
"We've only kept one clean sheet so far. I've given away a couple of penalties, which is very frustrating, but I suppose that's what happens if you're a defender," he said.
"Hopefully in a month's time we'll have kept a few clean sheets and if you ask me the same question I'll be a lot happier."
Everton are hoping that their stance as the underdogs this weekend will work in the Toffees’ favour as they prepare to face title contenders Chelsea. The two sides will face each other again just a week and a half after Saturday as well, in the Carling Cup.
