Ronaldinho insists he accepted his substitution in Barcelona's disappointing 0-0 draw in Osasuna yesterday.

"It was a hard game, very tough, but the result is not absolutely terrible," said the Barca ace. "Osasuna hoped to hit us on the break and we tried to create dangerous chances, but we needed luck and were not able to score.

"My substitution seems to me something normal, it is a decision for the trainer, and we know that this week we have another important game in the Champions League."
