Find out who stood out on the German's debut below.
✔️ GOOD PERFORMANCE
Rui Patricio: 7.8
Chelsea struggled creatively throughout but, when they did manage to carve out chances, Rui Patricio was on hand.
The Portuguese made five saves and was consistently decisive under crosses as the hosts tried to take the aerial route to goal.
He will have busier games, but there is no doubt Nuno Espirito Santo will be delighted with his goalkeeper's efforts.
❌ BAD PERFORMANCE
Ben Chilwell: 6.3
You can probably put Ben Chilwell's surprise when his number went up after 76 minutes down to the fact that managers don't tend to substitute full-backs.
But his withdrawal showed that Tuchel wasn't particularly pleased with the manner in which his No.21 had adapted to a new wing-back role.
The Englishman managed just two crosses (which compares particularly poorly to Callum Hudson-Odoi's 11 on the other wing) all night and missed arguably his team's best chance in the second half.
⭐ STAR MAN
Mateo Kovacic: 8.8
If Tuchel's plan is for his side to consistently dominate possession in this fashion, then he will like what he saw from Mateo Kovacic.
The Croatian made a match-high 150 passes, recovered the ball five times, and almost won it with a long-distance effort late on.
He could become a mainstay of the new manager's midfield.
