Touted as the ‘next Xavi’ - praise doesn’t come any higher for a young central midfielder - Thiago made 101 appearances for the Catalan giants before he was sold to Bayern for €25 million in the summer of 2013.
Pep Guardiola wanted Thiago to become his version of Xavi, while the player himself was keen to reunite with his old boss at the Allianz Arena.
It would be a gross exaggeration to claim that Thiago has reached the level Xavi did at his peak - he’s nowhere near that good yet - but he’s still impressed in Germany.
Moreover, he’s won a host of titles, including three Bundesliga winners’ medals and two German Cups.
The 25-year-old was in and out of the starting line-up under Guardiola but has featured regularly for Bayern since Carlo Ancelotti replaced the current Manchester City boss in the summer.
Video: Thiago's magnificent pass v Hamburg
And it was his glorious pass against Hamburg a week-and-a-half ago that resulted in Bayern’s most recent victory.
The ball bounced to Thiago who, with the outside of his right foot, sent a stunning pass from his own half right into the path of the unmarked Franck Ribery.
The French winger then squared for Joshua Kimmich to net the winner, in the 88th minute, with a back-post finish.
Best pass of 2016?
Some people on Twitter are claiming it might be the best pass of 2016 - and it’s got to be right up there as a contender.
If only he scored and set up more goals...
If one criticism could be made about Thiago, it’s that he doesn’t contribute enough goals and assists for a player of his quality.
If he could improve his numbers in that respect, he’d surely be widely regarded as one of the world’s best central midfielders - just like Xavi was.
