Chris Wilder has thanked CEO Stephen Bettis, the board and owner Prince Abdullah for their support and continued backing, following the announcement of new contracts for his captain and vice-captain on Wednesday evening.
Billy Sharp has penned new terms that sees him contracted until the summer of 2022, whilst Ollie Norwood has signed an improved deal which will run until 2023.
And Wilder says this could be the start of other influential figures penning new and improved long-term deals with the Blades.
He remarked: "I said at the start it wasn't the right time to talk about new contracts and signing players when the pandemic was starting to grip the country and the world, but we've seen some light at the end of the tunnel.
"We've had an outstanding season and obviously we want to keep that going, but there will always be medium and long-term plans and I'm delighted that Stephen (Bettis) and the board have cemented my vision of those boys and the others we intend to get nailed down in the near future.
"These boys have got us up to the top of the mountain, they key now is to keep improving the squad and every aspect of the club. Rewarding the likes of Billy and Ollie for their performances over the last two or three seasons is crucial because their time is far from up."
The Blades boss heaped praise on both players and has hailed their contributions on and off the field this term.
Wilder added: "They are both hugely influential players within our group.
"Every since I've been at the football club, Billy has been a major actor for us and it's been quite a difficult season for him, particularly at the start. But he understood that, got his head down and has led the group magnificently when he wasn't playing and with his current performances he's proved he's still got a lot to offer.
"Having someone like Bill around for the next two season is great for myself, the other players and for the football club.
"Ollie will delighted to have been given the opportunity to play in the Premier League having been binned twice by Fulham and Brighton, but he was never going to get binned by me. He was brilliant in the Championship and he's been outstanding for us in the Premier League.
"Both boys know we've got extreme competition for places in their positions and both have acknowledged they've got to be playing well to be in the team, but I believe they will continue to contribute going forward."
