But Fabregas reckons his side have already missed one chance to deliver a killer blow to Jose Mourinho's side and they cannot afford to do so again.
"We had our chances to make it 2-0 in Madrid," he told Barcelona's website.
"In the return leg we will need to be as effective as possible, because they are very effective. We have to be on target in front of goal if we want to get to the final.
"It's vital to score, we cannot go into the match and wait to see what happens. In last year's Cup Clasico return leg - we had a good result from the away leg - and we were nearly eliminated from the competition.
"Madrid are very dangerous and in order to go through we'll have to play the best football we're capable of."
Barcelona are chasing a treble with the Primera Division title all but sewn up, although their Champions League hopes are dangling by a thread after a surprise 2-0 loss away to AC Milan in the first leg of their tie.
