Fabregas, who was in attendance at Guardiola's press conference, wrote on Twitter: "Although I only was with [Guardiola] for 1 year it felt like a lot more. For me Pep was my hero as a kid and an inspiration as a manager. Thank you for the little time we spent, I will cherish it always.
"For Tito, I wish the best in this new opportunity that football has given to him. We were together when I was a kid and he is not just a great person but also an excellent manager."
A number of names were linked with the Barcelona job, including Athletic Bilbao boss Marcelo Bielsa. However, the Catalan club moved swiftly to appoint Vilanova.
