But what were the most important moments over the course of the campaign? Here’s a look back over the season at the games that won promotion for Chris Wilder’s men...
1. QPR 1-2 Blades
United had to wait until the third game of the season for their first win but finally got the ball rolling with a 2-1 victory over QPR as Player of the Year David McGoldrick bagged his first goal for the Blades. What a signing! Photo: JP
2. Blades 4-1 Aston Villa
United absolutely blew Aston Villa away at Bramall Lane, in what many lauded the best performance for years. Jack O'Connell, Billy Sharp, Mark Duffy got on the score sheet while Oliver Norwood netted his first Blades goal. Photo: Simon Bellis
3. Millwall 2-3 Blades
A second 3-2 win in a row that proved the Blades had a canny ability to find any way to win - a McGoldrick brace and one from captain Sharp sank Millwall at The Den back in September. Photo: Robin Parker
4. Blades 4-2 Wigan
Billy Sharp netted his first hat-trick for a decade as the Blades sank Wigan to stay at the top of the table with a two point gap over chasing Leeds United and Middlesbrough. Photo: Simon Bellis
