The striker says leaving Bayern Munich for Barca has rejuvenated him.
In an interview granted to the Polish magazine Kwartalnik Sportowy, he said: "In Spain, technical plays are more appreciated. In Germany, the focus is always on order, intensity and winning games. Here, every little technical trick or dribble is valued.
This transfer has been a "breath of fresh air that will help me not to feel tired in the coming years.
"When I saw how determined they were to sign me, I knew that this transfer was much more realistic than any of my previous links with Madrid.
"Living in Spain and playing in LaLiga was always a dream, not only in sporting terms but also in personal life.
"It's not as bad as I expected, people respect my privacy. Of course, Barcelona is a tourist place, during the season there are many visitors, so this could change. We are an active family, we like to walk."
