The Blues looked every bit the reigning champions in the competition as they brushed aside the Italian giants with a minimum of fuss, much like they did to Leicester City in the Premier League at the weekend.
Trevoh Chalobah opened the scoring with a smart finish as the ball dropped to him from a corner on 25 minutes.
Reece James continues his fine goal-scoring form this season on 55 minutes when he produced an excellent finish himself, drilling the ball past Wojciech Szczęsny from the right side of the penalty box.
The Blues were purring by this point and just three minutes later it was 3-0 as Callum Hudson-Odoi was played in by Ruben Loftus-Cheek to round off a superb team goal.
Substitute Timo Werner returned from a hamstring injury to come on in the second half and rounded off the scoring in stoppage time as he swept home an impressive square ball from Hakim Ziyech.
