The indications are City may do the same regarding Savinho, which is a further erosion of Guardiola's authority.
Pure and unnecessary speculation.
You can be certain all moves in and out are sanctioned by Pep. The tension between him and Viana or whoever at the club is exaggerated.
Only the chairman is above Pep, but he is clever enough to know Pep is a huge asset, so undermining him is completely out of question.
Reign the imagination and your doubts about Pep.
