Chesea keeper Cech convinced they can win Cup Double
Cech knows the potential of silverware will drive the players on to make light of what has been a disappointing campaign so far for Blues fans.
He said: "It's a big win because we wanted to qualify for the next round and I don't think this was the stage we wanted to go out of the competition.
"We made it hard for ourselves losing in Bucharest.
"When they made it 1-1 we knew we'd have to score twice but at the weekend we made up a two-goal deficit at Old Trafford, so at half-time we knew we could score the goals."
