The guardian did a article on how Pedro was under appreciated in Barcelona ,
even though he was doing great things.

He came to Chelsea and was treated like a God. Dude became a legend
in less than 3 seasons.

He was not appreciated or recognized the way he should have been when he
was in La Liga.....


“And yet those expectations remain surprisingly low. While Catalonia might be talking seriously about Pedro, it can feel as though few others are. Beyond Barcelona there is still an assumption that he is one of few players in the Barça team who is not really that good.

Pedro denies it publicly, but others insist that during the clásico Cristiano Ronaldo looked at him and said: "And who are you?" Even if the story is apocryphal – and it may be – it says something. Others would ask the same thing. When Fernando Torres left Liverpool for Chelsea, many wondered why he did not hang on for a bid from Barcelona. The answer was simple: there would not be one, because of Pedro.“
