Leicester City's English midfielder James Maddison celebrates scoring his team's second goal during their English Premier League match against Chelsea at the King Power Stadium in Leicester, central England on January 19, 2021.
Lampard responded by turning to his £85 million worth of talent on the bench as Werner and Ziyech were introduced for the final 25 minutes.
Werner has now gone 11 Premier League games without a goal and even when the German international did find the net to flick home a late free-kick, the offside flag rescued Leicester.
