Benfica winger Nicolas Gaitan is confident that Didier Drogba and Fernando Torres' failure to find goals can help the Portuguese side get past Chelsea, when the two sides meet in Lisbon on Tuesday, in the first leg of Champions League quarterfinals.

Moreover, Gaitan feels Benfica can dump their second English team from the Champions League this season after they topped the table and played a vital role in Manchester United's exit at the group stages.

"I think there is an anxiety in Chelsea by the lack of goals from Torres and Drogba. We can exploit that and even though it will be difficult to stop them, it is possible and I have confidence we will keep a clean sheet," The Sun quoted the Argentine as saying.

Chelsea have had problems finding goals this season as big-money signing Torres has scored only two goals in his last 26 matches and the usually dependable Drogba has netted just three times in the past three months.

"Benfica are having a good season in Europe. This is our main strength against Chelsea. The squad is convinced we can create chances and we play without fear against anyone," Gaitan added.
