Chelsea tasted victory for the first time in four Premier League outings with a 2-0 triumph at Hull City with William and Diego Costa produced fine second-half finishes.
The hosts enjoyed the better of a cagey first half but went behind when Willian swept home a curling shot after good work from Diego Costa after the break.
Costa found the top corner with a similar strike to double the lead after Nemanja Matic’s powerful run.
Hull never recovered and could have been further behind but for Pedro’s poor finishing from six yards.
Chelsea manager Antonio Conte promised “a solution” after his side went down with a whimper against Arsenal last weekend and he found his answer in a strategy he used at former club Juventus.
The Italian opted for a three-man defence during much of this trophy-filled time in Turin and deployed Gary Cahill, David Luiz and Cesar Azpilicueta at the back as he organised his Chelsea rearguard to match.
