Guardiola said farewell to Nou Camp fans after victory over Espanyol.
“Guardiola has taught me many things. He’s one of the coaches who has most influenced me. He changed my position and since then there’s been a before and after in my career," said Mascherano.
On Tito Vilanova, the Argie added: “Tito has been Pep’s shadow. He’s done a really good job as assistant coach to the extent that we noticed his absence when he was ill. He’s done a formidable job. Now, it’s his chance."
