Barcelona travel to Pamplona on Saturday having won all eight of their league matches this season, but the 25-year-old is confident that the hosts can cause an upset.
"The time has come. They have gone on a run winning many games back-to-back but I think we can nick a point off them," the Spaniard told reporters at a press conference. "They are not going to have a good time here.
"We are going to have our chances and we are going to try and take them. We can take advantage of [the Barca players representing their national teams] by playing an intense game, closing them down and doing a very good job in defence."
"Whether we can win the game is another thing because they have players of true quality."
Osasuna currently sit 18th in La Liga.
