I'd be curious to know if Bayern have agreed to the written clause (min exit clause dependant on pitch time) he had with us, and one he was allegedly negotiating with ManU, or Pep's sweet-talking was all that was required. Because if its the latter, Thiago could come to regret this decision. Verbal guarantees these days mean nothing. Its quite clear Pep is acting in his own interest, without much regard to Thiago's long term future. Pep wants to eliminate any complacency that could creep in at the back of a treble-winning season, by injecting more competition, and hunger in to the squad. Thiago, however, will still 've to earn his mins, and be on his A-game from the get-go. His nonchalance, and lapses will certainly not go too well with the partisan German media, and fans, considering there is zero margin for error in a treble winning team, and that his presence alone would be compromising the future of a local talent. And we know pep is a hard-task master, and whilst he can give you assurances, he's ruthless at disciplining the player if his expectations are not met, and for him the the name of the player is impertinent (including his own transfers).
Thiago still needs to mature his game, and current Bayern is not conducive. He needs freedom to play through his errors and a forgiving ambience. United would 've been better, outside Barca. Thiago's decision seems more an emotional than rational. Pep won't stay long at Bayern, and neither will Thiago imho. And i wont be surprised if he'd be seeking a new club in 2 years time. Lack of stability can ruin a player's career.
