The Spain international cannot wait to take on their next challenge in the Champions League, but admits they are expected to get beat
The Andalusians progressed to the last eight at the expense of Porto and the Spanish winger knows they will have to give everything in order to defeat a more experienced team in the form of Jurgen Klopp's men.
"Dortmund are a team used to playing in these type of games," the 31-year-old told uefa.com.
"They are a strong team who play good football; we will give 200% in order to qualify. We want the tie to come as quickly as possible.
"However, we will have a chance of getting through if we compete as we have been doing.
"We must give Dortmund our maximum respect."
BVB travel to Spain in the first leg on April 3 before La Liga's fourth-placed team go to Signal Iduna Park for the second leg on April 9.
