Goals in each half from Kai Havertz and Christian Pulisic earned defending champions Chelsea a solid 2-0 first-leg victory over Lille in the Champions League last 16 on Tuesday, but the London side will be concerned about injuries to key players.
Germany forward Havertz, who had already had two attempts on goal early in the game, headed down a Hakim Ziyech corner in the eighth minute and the ball bounced high off the turf into the net.
