The midfielder initially left the Catalan outfit for Roma on a two-year loan deal last summer, only to join Milan on Wednesday for the entirety of the 2012/13 season.
"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," Krkic claimed.
The 22-year-old went on to praise Guardiola for his guidance during a golden era for 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 (Lionel) Messi, (Andres) Iniesta and Xavi helped me a lot," he said.
Krkic added that he would like to remain at Milan even after his loan deal ends after enduring a tough time in Rome.
"I want to do well and help the team to stay here after the transfer," he said.
"In Rome I played little and to get to Milan is a step forward for me. I'm here to stay."
