Chelsea head into Sunday's game against the Premier League's bottom side with the aim of making it three wins on the spin. The Blues are overwhelming favorites to win the game after their 1-0 victory over Tottenham Hotspur in midweek.
Chelsea have improved under Thomas Tuchel and have recorded three wins and a draw under the German manager.
The Blues look better defensively, but their attack continues to be a source of concern. Several Chelsea forwards are going through a poor run of form, which may give Sheffield United a chance to get a result on Sunday.
Sheffield United are currently at the bottom of the Premier League table, twelve points away from safety. The Blades have, however, been impressive in recent weeks, winning three of their last five games in the league, which included a 1-0 away win over Manchester United at Old Trafford.
Former Manchester United striker Dimitar Berbatov has backed Sheffield to earn a draw against Chelsea on Sunday night. Writing in his column for Metro, Berbatov said:
"It may be too late for the Blades to pull off the great escape but at least they're fighting now."
"I think they can cause Chelsea problems here and take something from the match."
Chelsea looking to continue new-found momentum under Thomas Tuchel
A victory for Chelsea over Sheffield would see Thomas Tuchel's side leapfrog Everton and West Ham and move into fifth place, one point behind Liverpool, who occupy the last UEFA Champions League spot.
Tuchel will be desperate to improve on Chelsea's fourth-place finish in the Premier League under Frank Lampard last season but will have to do so without star defender Thiago Silva. The Brazilian defender has been who has been ruled out for this weekend's match with a thigh injury.
An away trip to Sheffield United, where Chelsea lost 3-0 last season, could prove to be a tricky test for the German's side, despite the Blades' current position in the Premier League table.
