Romelle Donovan was the Sheffield United goalscoring hero as his injury time winner secured the first victory of the season for the Blades at Bramall Lane.
United were a goal down after 30 seconds through Xavier Simons but equalised soon after through Japhet Tanganga.
Bolton went ahead again in the second half through Sam Dalby but the lead last just a minute as Patrick Bamford tapped in from close range.
the match looked to be heading for United’s fourth consecutive draw until the lively Donovan thundered in an injury time winner.

8. Romelle Donovan - 7
A ball of energy on the right. Didn't always make the right decision but he's so exciting to watch. Was a constant threat, always trying to drive forward and take on defenders. Unlucky not to score with his shot going just wide in the first half then finished superbly for the winner after switching to the left late in the second half | Simon Bellis / Sportimage
