Chelsea boss Thomas Tuchel said his side produced an "amazing performance" as the holders progressed to the last 16 of the Champions League with an impressive win against Juventus at Stamford Bridge.
Trevoh Chalobah, who was making his first European start for the Blues, scored the opener before Reece James controlled a clearance and volleyed across Wojciech Szczesny to give Chelsea the advantage their dominant performance deserved.
A third soon followed with Juventus looking shell-shocked as a short, sharp interchange of passes gave Callum Hudson-Odoi the chance to slot home at the back post.
The scoring was completed when Hakim Ziyech capitalised on a mistake from Juve midfielder Weston McKennie to cross for Timo Werner to tap home in added time.
