Not many teams have tested Chelsea's three-man defence this season, but Burnley showed there is a way to get at Antonio Conte's side.
The Clarets were extremely clever in Sunday's 1-1 draw, especially in the way they targeted Chelsea's left flank, which is far less disciplined defensively than their right side.
Eden Hazard always wanders inside from the left - far more than Pedro does when he starts on the right - which is what happened at Turf Moor.
That leaves Chelsea's left wing-back Marcus Alonso to advance up the pitch and give them an option wide on that flank.
