The former Barcelona coach's close friend has opted not to directly answer questions about a meeting with AC Milan CEO Adriano Galliani that reportedly took place.
The 51-year-old Estiarte worked as head of external relations at Barcelona during Guaridola's spell in charge of the Catalans, and he has a close relationship with the former Spain international. A report in Italian publication La Gazzetta dello Sport this week suggested that AC Milan CEO Adriano Galliani has met with Estiarte and Guardiola's brother Pere to talk about the ex-Barca coach's plans for the future, but Estiarte has remained coy on whether the meeting took place.
"Did I speak with Milan about Guardiola? It's not up to me to answer that question," Estiarte at the World Business Forum.
Milan released an official statement on Tuesday evening to deny the meeting, but rumors about the Rossoneri's interest in Guardiola continue to surface.
Estiarte also took the time to respond to Inter Milan president Massimo Moratti's recent claims that Barcelona is a boring team.
"I admire Moratti, and I was surprised that he said something like that," Estiarte said. "He can say that he doesn't like our style of play, but it's a bit disrespectful to say that Barcelona are boring."
