David Villa insists Barcelona's shock defeat to Hercules was a blip.
Barca go into their Champions League tie with Panathinaikos on the back of that 2-0 loss.
Villa felt the Hercules match was an "accident" that they should not dwell on, telling El Mundo Deportivo: "I think that's the right word (accident), above all at this stage of the season.
"It's something else if it had been in the Champions League or further on in the season, but in the second week you could say it was an accident that can be rectified.
"It's already forgotten, (although) we need to analyse the things that we did badly so that they don't happen again in the future."
He added: "I'm sure we are not going to go through many situations like the one against Hercules."
