They were then eliminated by eventual winners Bayern Munich after suffering a 6-1 thrashing on aggregate.
However, with Tuchel now in charge the Blues were much harder to break down against Atletico, with the La Liga side mustering just six shots and none on target.
Chelsea dominated possession and created more chances, with 11 shots in total and five on target.
Tuchel’s back five system has certainly had an impact, with Chelsea going unbeaten in all competitions since his appointment and conceding just two goals in those eight games.
The all-important away goal means Chelsea are in a strong position to reach the quarter-finals for the first time in seven years and Tuchel believes his side are well-equipped to go far in the competition.
