The full-back spoke after Sunday's 2-0 loss to Villarreal at Camp Nou
Dani Alves admitted Barcelona's players closed the season "sad" at being unable to beat Villarreal and adding that "we have to reflect and change the mentality for next season."
Speaking after the 2-0 defeat at Camp Nou, He said: "We have to put in more enthusiasm because we're representing these colours and a rich history. We cannot reach the end of the year without aspirations.
"We are very demanding. We have to go for more always. It's been an unstable season. Some good moments and not-so-good moments.
"We have to hold on to the good ones and not repeat the bad ones. That's the reflection we have to do."
On his own future, with his current terms up next month, he stressed his desire to stay.
"I don't know if it will be my last game," he said. "I live in the present, I don't think about the present.
"My desire is to continue because I can keep helping the club, but it does not depend on me, I have aspirations and will keep fighting."
