I think it's Sheffield Unifeds sixth season in league one. Coventry have just also got the record of 47 years without a top 6 finish.
It's a struggle to get out of this league only teams who have spent a large amount of money have gone straight back up in recent years such as Norwich Leicester wolves and Wigan. I can't see Bolton doing that well still under an embargo and their best asset Zach Clough will be sold. Whoever takes the Bolton job will have a massive task on their hand.
