Los Che go into the second leg of their Cup tie with a 2-0 advantage but the 27-year-old has warned his team-mates not to take anything for granted
Los Che have a 2-0 advantage going into the match, but the forward says his side must be careful and ensure they do not allow the visitors back into the game.
“The most dangerous element is ourselves, how we go out on to the field," the Spain international began. “We have a very positive result from the first leg, now we must finish them off.
“Osasuna do not give up, and despite the result from the first leg they are going to try and surprise us. I have no doubt that this will be a difficult game.
“We must go out to win any game that we play at Mestalla," the 27-year-old concluded.
