Their last top-flight meeting came in the 1975/76 campaign as Wolverhampton Wanderers comfortably beat Sheffield United 5-1 at home and 4-1 away that season. Both teams were unable to beat the drop to the Second Division that year
These two sides are separated by solely a point in the 2019/20 campaign. The hosts will look to continue with their unbeaten run after defeating Bournemouth 2-1 at Vitality Stadium.
Sheffield on the other hand, will fight to come away with all three points, having recently drawn their last two Premier League games against Manchester United and Tottenham Hotspur.

Wolves 1-1 home draw to United meant they remained seven points clear at the top of the Championship. It was then defender, Neil Collins who gave Mick McCarthy’s side the lead in the 19th minute but not long after, James Beattie levelled.
Man of the match was keeper Wayne Hennessey whose efforts weren’t kept to a minimal as he made two fantastic saves to extend Wolves’ unbeaten home run record.

The victory earned Wolves a seventh win in their last eight league games.
3. Sheffield United 0-2 Wolverhampton Wanderers, League One 2014/2015
The Wanderers delivered what at the time seemed a damaging defeat on Nigel Clough’s men to ruin their 125thanniversary celebrations to move closer to a return to the Championship.
The opener came in the 13th minute when James Henry’s cross eluded team-mate Dave Edwards and keeper Mark Howard.
Edwards doubled their advantage after the break and as a result, Kenny Jackett’s side ended an 11-game unbeaten run and a sequence of eight games without conceding for the home side as Wolves moved closer to the top of the table.
Wolves on the other hand held a ten matches undefeated run until their midweek loss to Crawley.

Wolves went into this game on a back of six wins from the nine opening games. But it all went wrong for the visitors whom in the past years had no problem in overcoming United.
Conor Coady was sent off in the 15th minute and Ruben Neves missed a penalty early into the second-half.
The win meant the Blades moved up to second place in the Championship table.

Still managed by Nuno Espirito Santo whose side maintained an 11-point lead at the top of the Championship table with a comfortable win over Sheffield.
Portuguese trio Ruben Neves, Diogo Jota and Ivan Cavaleiro secured all three points as Neves’ breathtaking right-foot opener into the top right corner gave the Blades keeper, no chance.
Jota then doubled the lead after Cavaleiro’s fine assist as he then added the third from a deflected free-kick, moments after keeper Simon Moore had been sent off for a previous foul on Jota.
The defeat meant Chris Wilder’s side fell to a second defeat in five days and were dropped to eighth place.
