Chelsea came out victorious after an impressive display against Lille in the first leg of their Champions League tie at Stamford Bridge.
Kai Havertz, who was the preferred option up front with Romelu Lukaku dropped, opened the scoring early on after netting a header from a corner.
The French side came back with some real gusto but never truly tested Edouard Mendy while Christian Pulisic scored after around an hour to put the Blues in cruise control.
