The diminutive playmaker has revealed just why he left Camp Nou back in 2013 having grown frustrated with a lack of playing time.
The 27-year-old has since gone on to become a huge success with the Bundesliga giants, winning five straight league titles and emerging as one of the finest midfielders on the planet.
Speaking to SER on Wednesday, he said: “I have always wanted to play and since that wasn’t possible with Barça I had to leave to find the joy in playing football again.
“To me playing is more important than winning a trophy, in the end, you always ask yourself ‘To what extent I have contributed to the win?’.”
Thiago is currently away on international duty with Spain and will take on Wales and England over the next week.

The Chile midfielder, 31, moved to the Nou Camp from Bayern Munich on a three-year deal this summer and has started twice in six appearances so far.
He has yet to last a full 90 minutes and admits to being “irritated” by the situation.
But Vidal, who is in Miami for Chile’s friendly against Peru on Friday, said he has talked things through with Barca coach Ernesto Valverde.
He told reporters: “I am not happy but if I have a problem with the coach I will say it to his face.
“How am I going to be happy if I don’t play, and me of all people? I am someone that has always fought, that has been in the best teams in the world, that has won everything and who wants to continue winning at Barcelona.
“I am fine physically and happy. In the past few games I have been a little irritated but that’s how it is, we will keep battling, there are a lot of important games ahead and we will see.”
