Oriol Romeu believes that Valencia can overcome Atletico Madrid in the second leg of their last-16 Copa del Rey clash on Tuesday.
The two sides are level at 1-1 from the first leg after Raul Garcia's effort was cancelled out by a late Helder Postiga header last week.
"We demonstrated in the Mestalla we can create chances and harm them," Romeu, who is on loan at the Spanish club from Chelsea, told Mundo Deportivo.
"We need to keep this going. In the first leg we had five or six clear chances on goal and could have had two or three goals. Now we want to do that at the Calderon."
Atletico have not lost on their own patch this season.
