Andres Iniesta worried by Barcelona defence

Barcelona midfielder Andres Iniesta has expressed his concern at the number of goals that the team has conceded this season.

The Catalan giants were breached for a 15th time in 12 La Liga games on Saturday as they defeated Real Zaragoza 3-1 at the Camp Nou.

"Football is a game between two teams, and our opponents come to play," said Iniesta. "We need to correct our errors so we don't concede as many goals and this is completely achievable."

Barca continue their Champions League campaign on Tuesday when they travel to Russia to face Spartak Moscow.
