Here’s a fuller account of what’s happened: which Championship manager was sacked after defeats to Millwall, Middlesbrough and Ipswich Town — what led up to it — and what the fallout has been.

If you like, I can also pull some direct quotes & reaction from the club/fans to flesh it out a bit more.

What happened

• Club: Sheffield United

• Manager: Rubén Sellés

Sellés has been officially sacked by Sheffield United following a disastrous run of results to start the 2025/26 Championship season.(TalkSport)

The build‑up: what went wrong

1. Poor results from the start

   • The club lost their opening league matches: five straight defeats in the Championship.(The Guardian)

   • They also suffered heavy defeats, including 5‑0 at Ipswich Town.(BeSoccer)

1. Key defeats against Millwall and Middlesbrough

Among the list of losses under Sellés were matches versus Millwall and Middlesbrough, which compounded the pressure.(TalkSport)

1. • The loss to Ipswich (5‑0) was especially damaging, given how heavy and embarrassing it was, and it seems to have been the final straw.(BeSoccer)

2. Underlying issues

United had not scored many goals (in fact, very few) and had a very poor goal difference.(BeSoccer)

• • There was also concern over the style of play, consistency, and whether the squad was being well managed tactically.(BeSoccer)

The sacking

• When: Rubén Sellés was dismissed after the Ipswich defeat.(Reuters)

Length of tenure: Sellés had been in charge for under three months, having taken over in the summer.(TalkSport)

• Reason given implicitly: The club was bottom of the Championship table, with zero points at that stage, no wins, a very poor goal difference and inability to score. The Ipswich result was probably decisive.(BeSoccer)

Aftermath & what the club did

• Replacement: Sheffield United reappointed Chris Wilder as manager. This is his third spell with the club.(Reuters)

• Contract: Wilder was given a contract through 2027.(The Guardian)

• Expectation: The club made clear that promotion remains their ambition, and they appear to believe Wilder is the man to steady the ship, reverse form, and restore confidence.(The Guardian)

Why this matters / what it reflects

• For one, it’s an early example in the 2025/26 season of how little patience there is at the Championship level — especially from clubs with high expectations and investment. A string of bad results and a heavy loss can trigger action quickly.

• It shows how decisive heavy defeats (like 5‑0) are, even more so when combined with other bad results and poor underlying stats (goals scored, goal difference).

• The fact that Sheffield United turned back to Wilder, someone recently dismissed, underscores the tension between wanting fresh direction vs returning to a known entity in crisis.
