Despite making costly additions, Chelsea has struggled this season once more. However, manager Mauricio Pochettino has urged patience, which was put to the test in a slow first half at Stamford Bridge.

In the 54th minute, Palmer scored the first goal from close range following a rapid break by Raheem Sterling, who sent a low pass in front of the goal.

Jackson extended the lead seven minutes later with a simple tap-in at the far post. Sterling was once more involved. He attempted to poke the ball past Wes Foderingham, the goalkeeper, but Palmer caught it and delivered it to Jackson by the goal line, avoiding a leaping Foderingham.

Enzo Fernandez, an Argentina international, was not included in Pochettino’s starting eleven but was added as a substitute in the 69th minute.

Chelsea moved up two spots to tenth place with its second victory in the last six league games.

Christopher Nkunku did not see action for Chelsea as a substitute. After undergoing knee surgery, the forward for France is back.

In a League Cup quarterfinal on Tuesday, Chelsea will host Newcastle.

Sheffield must work hard to escape the relegation zone. The Blades, who have only two victories in the league, visit Aston Villa on Friday.
