The visitors took a fifth-minute lead when a headed clearance fell to Arblaster, who connected with a sweet right-footed volley from just outside the box which gave City goalkeeper Sam Tickle no chance.

It proved enough to settle a contest high on endeavour but low on entertainment from which the Blades emerged worthy winners.

For the Robins it meant a second home defeat in the space of four days without scoring a goal and their fans were quick to signal their frustration after nine minutes of stoppage time.

City midfielder Luke McNally made his first start in a home game since February 2025 when he sustained a serious knee ligament injury.

Yu Hirakawa and Rio Cardines also came in, while Blades manager Chris Wilder made five changes, bringing in Arblaster, Mark McGuinness, Harrison Burrows, Kalvin Phillips and Jordan Ayew.

The first half might have been a different story had Hirakawa capitalised on a golden opportunity to put City in front after four minutes. The winger broke clear, but with the goal gaping miscued his shot straight at United goalkeeper Michael Cooper.

The miss was made to look more costly when Arblaster fired United in front a minute later and they went on to look the better side in the opening period, winning most of the physical battles and easily nullifying City’s predictable attacks.

Hirakawa did break away again in the 13th minute, this time going down under challenge inside the box but referee Ben Speedie waved away his penalty appeals.

Tom Cannon volleyed wide for United and Liam Kitching was unlucky to see a 27th-minute effort blocked for a corner as the Blades looked the more threatening outfit. The half-time whistle brought loud booing from City supporters.

Home boss Michael Skubala made two attacking changes at the start of the second half, sending on Elijah Adebayo and Jed Wallace for Scott Twine and George Tanner, but still his team failed to create much until two chances in quick succession in the 65th minute.

A Wallace shot was blocked by Burrows and from the resulting corner Dom Ballard headed over at the near post.

Soon United were pressing at the other end and Tickle did well to smother a Japhet Tanganga header on his line.

It was the visitors who looked more likely to score in the closing stages, Cannon having a shot blocked into the path of substitute Ryan One, who fired over from the rebound and also sent a late header wide.

City remained toothless and could have no complaints over the result.
