The Spaniard spent eight years at Arsenal after Wenger convinced him to leave Barcelona’s La Masia academy.
Fabregas’ time in north London saw him win the FA Cup and the FA Community shield before he moved back to Barcelona in 2011.
After three years in his homeland he complete a move to Chelsea where he worked under Jose Mourinho.
But the 29-year-old is most grateful to Wenger for bringing him to England.
“Arsene Wenger was probably the most important because he gave me the real chance, the chance that everyone needs and everyone wants,” Fabregas told FourFourTwo.
“After that it’s up to you to prove that they are right, they are wrong, it’s in your hands, but he gave me the chance.
“He took me when I was only 16 – he made me a better player, a better person. I always considered him like a father figure, like a second father.
“The way he treated me it’s not normal nowadays in football because everything is so fast, everyone is so impatient – you need results now.
“And for that Wenger is a special manager and a special person, and without him I wouldn’t be here right now.”
Fabregas did reserve some special praise for now Manchester United boss Mourinho however.
“Working with Mourinho was fantastic,” he added.
“His passion for football, his character, his ambition to always win every three days is not easy.
“The way he pushes his players to be better every day is what impresses me the most – it was a really fantastic experience.”
