Chelsea reduced Southampton to six efforts overall, with one on target in addition to James Ward-Prowse’s converted spot-kick. He, Adam Armstrong and Theo Walcott had two shots each.
Although it was Chilwell who gave away the penalty, he balanced that out with his contribution at the other end and in addition to threatening the Saints net directly, the left wing-back made three key passes and put over seven crosses, two of which reached a team-mate – accuracy that was better than anyone else.
As the average position maps indicate both Chelsea wing-backs, Chilwell especially, spent time away from the touchline, tucking inside to help a midfield that was up against plenty of Southampton bodies in the middle of the park. Rudiger and Chalobah went wider on occasions, and up front, Werner on the right operated close to Lukaku in the middle.
