Barry Robson says the Blades are determined to make it a South Yorkshire promotion treble later this month.
Following Doncaster Rovers and Rotherham United winning promotion last weekend, Robson insists the Blades desire to complete the job via the play-off is as strong as ever:
"There have been celebrations in the region this week, congratulations to Doncaster and Rotherham, but we want to make sure it is Sheffield United celebrating at Wembley later this month.
"Every way is a great way to win promotion, but obviously everyone says it is extra special to do it at Wembley.
Analysing the first obstacle in the way of that ambition, Robson added: "Everyone probably says the same about Yeovil, but their front two are very dangerous.
"They must have had a good season to have finished fourth after 46 matches, they are certainly there on merit. Yeovil will fancy their chances and like us they will see this as a great opportunity to play at Wembley again."
