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.
9. Ben Brereton Diaz - 7
Can see why Wilder is a big fan. Such a clever footballer, his movement and touch at times was excellent and when he gets on everyone else's wavelength he should be a really key player this seaosn for the Blades. Tired towards the end | Sportimage
10. Patrick Bamford - 6
Should have scored in the first half but just couldn't get the ball out fo his feet and his effort was blocked on the line. Linked up well with Campbell at times in what was a largely positive partnership. Perfectly positioned to tap in the second equaliser | Getty Images
11. Tyrese Campbell - 6
Much better from Campbell. Showed superb skill to ntmeg a Bolton defender and set up Bamford whose shot was blocked but overall he looked sharper and hungrier. Linked well with Bamford but also with Donovan at times when he pulled out wide. Came off for Cannon on the hour | Christof Koepsel/Getty Images
12. SUB: Kalvin Phillips - 6
On for Riedewald after an hour and did what he does. The sooner he's able to start and finish a match the better for United. Played a superb ball in for Donovan's winner | Sportimage
