Chelsea boss, Enzo Maresca, said the club has to win trophies after his team has beaten Copenhagen to enter the last eight of the conference league.
Chelsea has stuttering for the form since Christmas and was again far from their best against the Danes.
They were withdrawn at halftime after 45 minutes who saw them missing from having a single shot.
But the introduction of Cole Palmer helped to encourage them in life and the excellent solo objective of Kiernan Dewsbury-Hall was sufficient to set up a quarter-final with Legiaa Warsaw.
Maresca said: “It is important to reach the quarter -finals. Now the target is the next step which is the semi-finals. We deserved it on two legs. We changed and adjusted in the second half and we were much better. You need patience.
“This club has always won trophies in the past and we have to do our best to reach our goal this season. We have to give fans and club a title. »»
The quarter -final will be played on April 10 and 17.
