Relegated Bolton Wanderers need to make changes throughout the club, including looking at the whole squad for next season, says captain Darren Pratley.

Saturday's 4-1 loss at Derby confirmed their fall into League One.

It will be the first time that Bolton have played in the third tier of English football since 1992-93.

"Every day there is something negative coming out of the club and it needs a whole new change, probably a whole new squad," said 30-year-old Pratley.

He told BBC Radio Manchester: "Upstairs the finances seem like they're sorted now and there needs to be a positive vibe around the whole club as the last couple of years have been negative.

"Everything that has been going on, obviously it has been in the changing room whether you want it to or not - you can come out and say it doesn't affect you but it does."

"It's been a terrible season on and off the pitch, not good enough and we're going down," added Pratley.

"We have to take responsibility as players. On the pitch it's not been good enough, off the pitch as well people have to take responsibility upstairs.

"Let's not kid ourselves - this has been going on for a couple of years now. Serious changes and things need to be made next season if there is any change of getting out of League One."
