In just 10 minutes, Kai Havertz doubled his Premier League goal total for the season.
Despite not offering much in the opening period, the Blues cruised past Burnley after the restart to emphatically ensure the three points would be returning to west London come Saturday evening.
Havertz's last league goal came against the same opposition in November, converting a Reece James cross. This time it was another header, a back post flick from a perfectly weighted Christian Pulisic cross to validate his start over Romelu Lukaku.
