Juventus fullback Andrea Cambiaso says the fans had a right to jeer during Monday's defeat at home to Udinese.
Juve lost 1-0 last night, leaving home fans furious.
Cambiaso said: "No one expected a match and a result like this. We lacked the determination to score goals, in the second half we were too tense.
"No, we work for our path and to get to the Champions League. We found ourselves fighting with Inter but we must not panic and continue our path with clarity.
"We are Juventus, burdens and honours, the coach always tells us. Here a draw seems like a tragedy, and we've got one point in three games. We have accustomed people to a certain type of game and result, today it went like that. They (the boos) don't surprise me."
