Chelsea Boss Enzo Marceka says the club needs to win the trophy after the club defeated Copenhagen to enter the last eight of the Confederation League.
Chelsey has stumbled for the form from Christmas and was the best against Denns again.
After 45 45 minutes, they were pushed in half a time so they did not get a single shot on the goal.
But the introduction of Cole Palmer increased their lives and was enough for the semifinal round with the excellent single goal Legia Warsa of the Kunarine Dusbury-Holl.
Marska said: “It is important to reach the semifinal round. Now the target is the next step that is the semifinals. We qualified it on two legs. We changed and adjusted in the second half and we were much better. You need restraint.
“This club has always won the trophy before and we need to make our best to achieve our goals this season. We have to give the title of fans and clubs. “”
The quarter finals will be played on April 10 and 17.
