It's the Blues against the Blades this weekend, and we begin our preview of the game by taking a closer look at all the noteworthy numbers regarding Chelsea and Sheffield United...

Chris Wilder’s side were unbeaten against Chelsea last season. Their most recent defeat to Chelsea was when they were last in the top-flight in 2006/07. On that occasion, Jose Mourinho’s Chelsea side won both home and away, 5-0 on aggregate.

The Blues and the Blades meet for the fifth time at Stamford Bridge in the Premier League. Fifteen goals have been scored in the previous four, an average of 3.75 per game.

Chelsea stats

Chelsea are looking to extend our unbeaten run to eight games since we were eliminated on penalties to Tottenham in the Carabao Cup. Our only defeat in 90 minutes this season (12 games) was against Liverpool when we played the last 50 minutes with 10 men.

Frank Lampard’s side have won seven and lost one (Liverpool) of our past nine Premier League games at Stamford Bridge.

Chelsea have scored with 18.8 per cent of our efforts on goal (16/85), the third highest success rate in the Premier League this season.

Frank Lampard’s side have kept five consecutive clean sheets for the first time since September/October 2010, when Petr Cech was in goal.

Edouard Mendy has kept six clean sheets in his seven appearances for the Blues and has only conceded one goal which was on his debut against Tottenham in the Carabao Cup.

Mendy is seeking to be the first Chelsea keeper to keep four clean sheets in their first four league games for the club. Mendy has joined Cech and Neil Sullivan as the only Chelsea players in our history who have kept three clean sheets in their first three league appearances.
