Here's a look at nine quality players from the Championship that the Blades could sign this summer, who could prove to be bargain transfers, and have shown the potential to thrive in the Premier League.
1. Antonee Robinson - Wigan Athletic
The dynamic left-back came mighty close to joining AC Milan in January, and is unlikely to stick about now the Latics have dropped into League One. The USA international would be a quality signing. Photo: Lewis Storey
2. Dael Fry - Middlesbrough
The U21 international has had a tough season with Boro, but there's a reason why the likes of Chelsea and Man Utd have been linked with him in the past. He has the potential to be a future star. Photo: Jan Kruger
3. Matty Cash - Nottingham Forest
The 22-year-old has been linked with a host of elite sides, due to his potential and versatility. He's a fantastic right-back, and with Forest just missing out on the play-offs, could push for a top tier move. Photo: Nathan Stirk
4. Oli Watkins - Brentford
If Brentford don't make it into the Premier League, there's likely to be a transfer scramble for the prodigious forward. He was converted from a winger to striker last summer, which has seen him score 25 league goals. Photo: Ashley Allen
