Rhian Brewster finally broke his Sheffield United duck as the Blades advanced to the second round of the Carabao Cup following a 1-0 victory over Carlisle.
Brewster's first goal for the club since his transfer from Liverpool last summer separated the two teams, giving Slavisa Jokanovic his first win as manager.
Billy Sharp had an early effort blocked and Kacper Lopata saw his towering header saved by Lukas Jensen.
Brewster opened the scoring in the 24th minute, applying the finish after Sharp's shot was saved.
