The Spanish champions have won just one domestic match this season, with the Blaugrana recording four victories in as many matches.
And the World Cup-winning midfielder is surprised at how large the gap has become so early in the campaign, but is refusing to get carried away.
"The difference [in points] is striking," he told Mundo Deportivo.
"But La Liga is another matter. We play every game without looking at how the other [teams] fare. It is insignificant what the others do.
"We have to look at ourselves only."
The Spaniard went on to voice his concern after club-captain Carles Puyol sustained a knee injury in the Spanish capital, and now faces up to six weeks on the sidelines.
"It's a big blow because he is our captain," he explained. "He remains optimistic, but tests have confirmed [the injury]."
Barcelona currently sit two points ahead of Malaga in the Liga table.
