Marca says Barca are expected to soon announce Thiago will be leaving this summer.
The midfielder, who finished the U21 Euros as Player of the Tournament, has a concrete offer from Manchester United, but interest from Pep Guardiola's Bayern Munich is threatening the Premier League club's hopes.
Thiago can leave Barca for his €18 million buyout clause, which was an option in his contract should he have failed to be a first team regular last season. The original clause was set at €80 million.
Surprisingly, it's claimed coach Tito Vilanova was unaware of the clause in Thiago's contract.
