Speaking in South Africa, Fabregas first repeated his desire to stay at the Emirates next season, saying: "I am happy at Arsenal and I want to win titles there. But these things are not necessarily up to me.
"I am happy that we made it to the Champions League semifinals and, in general, things went well."
But when asked about his schoolboy hero and now Barca coach Guardiola, Fabregas told the Spanish newspaper El Mundo Deportivo: "If Guardiola called me it would be different. I would be delighted to go.
"Pep was a role model for me. I have always played in his position and that's why I first wore the No 4. He was my footballing hero when I was small."
"We have all played together for Spain before so I think there is always room for it to work," he said.
