Sheffield United have made the joint worst start to a top-flight campaign since 2014 having taken just one point from their opening eight games.
Here, the PA news agency takes a look at what has gone wrong for the Blades following their ninth placed finish last term.
Post-lockdown syndrome
The failure to replace O'Connell in the transfer market looks like a big mistake as they are making defensive errors that just did not happen last season. But Wilder cannot say he was not backed in the window as he spent £18million on goalkeeper Aaron Ramsdale before spending a club-record £23m on Liverpool's Rhian Brewster – a striker who had not scored a Premier League goal before and has yet to hit the ground running. Ethan Ampadu and Jayden Bogle have not yet made much of an impact either.
Tough fixtures
For all their own problems, the Blades have had it tough in terms of the games they have had so far, which may distort the table. Their last three games have seen them lose to Liverpool, Manchester City and Chelsea – teams who will be fighting for the title – while also playing Wolves, Arsenal, Aston Villa and Leeds when they were playing well. Their only opponent played so far who will likely be around them in the table has been Fulham and they drew 1-1. Wilder has said that their next 10 games, which include playing the likes of West Brom, Burnley, Brighton, Crystal Palace and Newcastle, will decide their season.
