A change in tactics
In Graham Potter's opening Chelsea match, followers of the Blues were treated to a surprise when Raheem Sterling was positioned as a wing-back and given its success nobody would have ruled out it happening against Crystal Palace.
Chelsea's new head coach opted for two changes from the Champions League clash with Ben Chilwell replacing the ill Marc Cucurella and Wesley Fofana coming into the side instead of Cesar Azpilicueta. Chilwell was not handed the same duties on the left of a back three like his Spanish teammate, as Chelsea played a back four at Selhurst Park, something Thomas Tuchel was reluctant to try.
