Barca finished as Spanish Liga champs.
"If you win the title, it cannot be a bad or average season, and considering that there were many complications, the emotional element is even more valuable," he insisted.
"It's true that we lost the Champions League in the semis but that let us know that we need to improve.
"The team have won confidence and credit. We had a great team like Madrid chasing us but we didn't give them a chance. We got 100 points and that would be impossible if we had lost our ambition.
"My only objective is to grow as a player. And I believe I have. I'm feeling very good and I can do more things than before."
