The Red Devils have made a habit of coming back to take all three points from losing positions this term – but instead it was the visitors who found a second wind.
Sheffield United produced one of the shocks of the season as the Premier League’s bottom side recorded a 2-1 win over title chasing Manchester United at Old Trafford on Wednesday evening.
It was an energetic, tireless, cohesive performance from the Blades, reminiscent of the displays that they had turned in on a weekly basis last season.
Chris Wilder’s side took the lead after 23 minutes, former Manchester City academy product Kean Bryan rising highest to head home from a corner.
However, the goal was not without controversy, with Billy Sharp not penalised for a nudge on David de Gea in the buildup. Minutes later at the other end, a foul was awarded against Harry Maguire following a similar incident.
It was the only complaint United could muster after a flat first half performance.
But the Red Devils fought back and found an equaliser in the 64th minute, former Sheffield United academy product Maguire escaping the attentions of the excellent Phil Jagielka and powering home a header.
United twice failed to clear their lines and Oliver Burke was presented with all the time and space in the world inside the box to fire towards goal, and his effort deflected in off Axel Tuanzebe.
It was a glorious piece of completely calamitous defending from the Red Devils.
It was calamitous defending against a side with just one Premier League win and ten Premier League goals to their name prior to Wednesday evening.
It was ultimately a poor performance from Manchester United, who missed the opportunity to return to the Premier League summit and brought an end to their unbeaten top flight run.
The result and manner of the defeat also led to fans questioning their title credentials.
But take nothing away from Sheffield United, who produced a stunning performance from front to back. The midfield three of John Lundstram, Oliver Norwood and John Fleck were absolutely everywhere, while their three centre halves were absolutely imperious.
