Chelsea won in the Premier League for the first time since August at Hull City, who are now without a top-flight win in five attempts.
Willian and Diego Costa produced fine second-half finishes as Chelsea tasted victory for the first time in four Premier League outings with a 2-0 triumph at Hull City.
Antonio Conte's side performed fitfully in their 3-4-3 formation during the early stages and Thibaut Courtois was the busier of the two goalkeepers before the break.
Warnings from former Italy boss Conte that the 2014-15 champions could be set for another mid-table finish without improvement this season were cutting a little too close to the bone at that stage but his players showed their quality in a clinical display after half-time.
