The Bianconeri had already booked their place in the Round of 16, but this was a head-to-head for the top of the group, which in theory should provide an easier draw in the knockouts.
Unlike the 1-0 defeat in Turin, Chelsea dominated from start to finish and ran riot with goals from Trevor Chalobah, Reece James, Callum Hudson-Odoi and Timo Werner.
“We wanted to stay patient but at the same time not fall asleep. We wanted to increase the rhythm and intensity. It’s so tough to create and score but we created so much. An amazing performance and a fantastic result,” Tuchel told BT Sport.
“We were sharper than in Turin, we took more risks, something we lacked in Turin. By control you cannot hurt them you need to penetrate with runs off the ball. We were very good and scored nice goals.
“I feel very aware that we do the invisible work and when we have to defend we really defend and dig in.”
N’Golo Kante went off injured in the first half, followed after the break by Ben Chilwell, who seemed to sprain his knee.
“Ben has a sharp pain in the knee. N’Golo twisted his knee a little bit. They will both be examined tomorrow. They are very sad things because N’Golo was very good before he went off and Chilly has been in a fantastic moment.”
“As a young kid, I was watching the Champions League. To now be involved and get a goal… It’s been very emotional.”
