The team's performance was a positive one, according to their coach Enzo Maresca, who acknowledged that it was not an easy win.
"The performance, for me, was good," Maresca said. "It was not easy and until we scored the first goal, it was difficult to break their defensive line down."
He added that the team was patient and waited for the right moment to score, which made the game easier for them after the first goal was scored.
Chelsea will now face Benfica on Saturday in the round of 16 of the tournament.
According to Maresca, the win is an important achievement for the team, as it shows that they have made progress and are now one step closer to their target.
"It’s important for us because 32 clubs started in this tournament, now we are going down to 16.
"There are clubs in the last five or six years that have played Champions League finals, like Atletico Madrid, who are back home.
"So we need to be proud and happy – and now we are in the Round of 16, the target is to go through to the last eight."
