Sergio Busquets has voiced his concern with the amount of goals Barcelona have conceded in the opening months of the 2012-13 campaign.
The Catalans sit top of the Liga table with 31 points from 11 games, but have already conceded 14 goals up until now, and Busquets has admitted that they struggle in defence.
"The only problem is the goals we're conceding. The opponents push us back a lot as well and it's hard for us," the holding midfielder told Cadena Cope.
"It's a shame because you don't enjoy it. We all like to pass the ball around, for there to be spaces. You're left without many options. We have to try and make the most of the chances we get.
"It's also true that we've had injuries to some defenders."
The 24-year-old then went on to stress that Tito Vilanova is doing a fine job at Barca as not much has changed since the departure of Pep Guardiola.
"We're fine with Tito," Busquets added. "Maybe he gets less media attention and that means things are calmer, but we have a very similar coaching staff."
Barcelona resume La Liga action on Saturday when they host Real Zaragoza.
