What bothered Pedro is that Robert statements were to justify the substitution
As Weloba could know, Pedro had no physical problems to play the UEFA Super Cup and his desire was to be starter. In the press conference after the match Luis Enrique said that the player had abandoned a training with some discomfort on his leg, but people close to the player say he was absolutely fit, as "he showed scoring the goal of the victory."
Pedro's substitution in the match vs Sevilla and Rafinha in the starting lineup can be understood, according to sources close to the player, as a decision of Luis Enrique to manage the squad. Knowing that he likely end transferred, the coach preferred to lineup players that will stay in the team, like the Brazilian, so his confidence increases.
Regarding technical director, Robert Fernández, words, which Pedro found "inappropriate," people close to Pedro say that the player told Fernández he wanted to leave during the US tour. What bothered Pedro was that these words were used to justify his substitution in the UEFA Super Cup.
Pedro is still thinking on leaving, as he knows that even doing things really well, he will always have Messi, Neymar and Luis Suárez in front of him. This is the only reason for the departure, since Barcelona is the club of his life and, as he said after the Super Cup, he will always be Culé.
The negotiations between Barcelona and Manchester United are making progress and they can reach an agreement at any time. At these moments, Barcelona still asks for €30 million, the clause of the player, and Manchester United proposed a price with variable numbers, which could even exceed this €30M.
Pedro Rodríguez was the protagonist of the match for the goal of the victory and also for his seriousness when celebrating the title. He was seen separated of the group when they got the trophy.
