Zidane bemoaned his side's lack of goalscoring prowess as to why they left Bilbao with only one point instead of three.
This time, he saw his team held to a draw against Athletic Club at San Mames.
"Compared to last year, results are changing.
"I see the game today and I can't say that we play differently to last year.
"Last year there were games we won in the last minute and this year we can't do that.
"I'm not concerned but I'm disappointed for the players.
"My job is to make sure we are positive and playing so that the goals will come."
