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.
1. Michael Cooper - 8
Didn't have loads to do in the first half but was forced into action to make a fine save early in the second half. Made another later on to touch onto the crossbar which he then headed away to safety. Made another few late on, too to cap off a fine display | Sportimage
2. Hamza Choudhury -5
Got off to a shocker of a start in the build up to Bolton's very earlier opener and gave away another big chance just before half time. Never really settled into the game nor looked comfortable at right back
3. Japhet Tanganga - 6
Needed to be more assertive for the Bolton opener but made up for it with a fine equalising header. After that it was a fairly typical Tanganga display | Getty Images
4. Mark McGuinness -6
Always keen to be on the ball to begin attacks from the back and his passing was sharp. Defensive covering was largely decent throughout but looked to have lost his man for Bolton's second | Sportimage
