The Blades established these links back in 2016/17 – Chris Wilder’s first season as manager. It resulted in Jamal Blackman joining them on loan the following year.
Now United have returned to the Premier League themselves, it is rumoured Wilder is going to make the most of his connections.
A potential transfer ban at Stamford Bridge could complicate things, however. The Sun is already reporting the likes of Tammy Abraham and Kurt Zouma will not be loaned out again if the club is unable to make new signings.
So here are three Blues players who could potentially benefit the South Yorkshire club – and who they could realistically sign.
Landing James would be a massive coup, what with the Independent reporting Manchester United are considering a shock move for the right-back.
Chelsea themselves may even give the 19-year-old a chance in their first team after an impressive year at Wigan Athletic, which resulted in him being named in the Championship team of the season.
With the ability to also play in central midfield, this versatile full-back would be a great addition to Wilder’s squad.
Another who could be given a chance by the West Londoners are impressing in the second tier of English football. The Daily Mail reports the club have applied for a visa so Mount can join them on their pre-season tour of Japan.
Another stumbling block could be if Derby County are promoted via the playoffs. They play Aston Villa in the final on Sunday (May 26).
Under Blues legend Frank Lampard, Mount has excelled at Derby this term. Yet if they don’t go up, suddenly the Blades will seem like a more attractive prospect.
Like Mount, Tomori has also stood out while on loan at the Rams in 2018/19. This has lead Celtic to show interest in the centre-back – according to the Mirror.
Tomori has been named Derby’s player of the year of his performances; which have helped the club to the aforementioned playoff final.
Like Mount, the 21-year-old could be tempted by the Blades should Lampard’s side not achieve promotion.
