Ronaldinho was named in Barca's squad for their Champions League clash against Stuttgart, having missed the last three games with injury problems.
He told El Mundo Deportivo: "It has bothered me because for five seasons I have always acted the same way. It bothered me, but it's normal, life isn't always wonderful.
"I am happy because I know I am focused and will deliver my answers to all this talk on the pitch. That's where I will respond to them.
"I know how to behave. I know when I can go out and when I must stay in. I have always lived the same way."
Ronie added: "Everyone knows who I am. Everyone knows what I do, how and where I act. It's been the same for the last five years."
Asked about claims that leaking from Barca management has been the cause of his bad press, Ronaldinho said: "The squad is united, that's all that matters. Every day in training my teammates treat me well, that's the most important thing."
