The new Barcelona goalkeeper failed to keep out an effort from distance in the late stages of the game but he and coach Luis Enrique insist that it is no big deal
The Chilean flapped at Blerim Dzemaili's shot from distance as the Italian side took the lead with 10 minutes left on the clock.
Bravo acknowledges that his concentration dropped in the build up to Dzemaili's effort but stressed that it is normal for goalkeepers to make such errors.
"I was enjoying a comfortable match and the little that I had done was comfortably dealt with," he told reporters after the game.
"The goal was my mistake, definitely a lapse in concentration. You have to learn to live with these things. I haven't had a lot of time to train but that's no excuse.
"It's not the first time it has happened and there is no goalie who has not made mistakes."
Barca coach Luis Enrique insists that he will not make too much out of the error and refuses to blame Bravo for the defeat.
"He was having a solid game, without doing anything silly. He saved a great chance from them and did well with the ball at his feet," the former Celta boss said of the Chilean.
"We're not going to analyse anything, other than the fact that, if the strikers had converted their chances, then probably we wouldn't be talking about this right now."
