Andre Iniesta says Barcelona must not lose their focus.

He says Barca can not fall into the trap of believing they have already won the league.

"We would be mistaken if we thought that the league is won. The situation is very good, but I am convinced that if we start believing that we can't lose, then it will surely happen," he said in an interview with Catalunya Radio.

"Here you play and you have the ultimate to give it your best."
