"I have not heard Guardiola. But someone from Camp Nou has told me he wants to come here [to Milan], but I cannot say who it is," he claimed.
The 22-year-old went on to praise Guardiola for his guidance during a golden era for the him and the club.
"I've learnt everything I know from Barcelona. I played four years that I could only dream about, to play with Messi, Iniesta and Xavi helped me a lot," he added.
