The creative midfielder has experienced life at both clubs but sees notable differences in playing styles.
The possession-based style of play adopted by Pep Guardiola at Bayern is often compared to that of the Spaniard's Barcelona team between 2008 and 2012, but Thiago has dismissed that comparison.
"I had to change my Barcelona style a bit when I got here. It's a different type of football. But that's only improved me as a player," Thiago told TZ.
The 22-year-old then revealed his happiness with life in Germany following his summer move from Barca.
"Some of my former Barcelona teammates have already visited me here," he went on. "I am feeling very well here and that's what I've told them as well.
"I didn't have any expectations when I joined Bayern. I had never expected that everything would have been perfectly organized like this."
The Spain international had 185 touches of the ball during Bayern's 5-0 win over Eintracht Frankfurt at the weekend - breaking Bastian Schweinsteiger's Bundesliga record - but he has insisted that it is much more important to him that he is getting to understand his teammates' movement and behavior on the pitch.
"I don't really care about how many touches of the ball I get," he said. "What matters to me is that I understand my teammates on the pitch.
"I am slowly starting to get to grips with how the guys are behaving in certain situations and where they want to receive the ball. That's important to me."
