Fabregas, who moved to Barcelona last summer, recently claimed that he tried to do everything on the pitch at Arsenal.
"Now, my teammates are more experienced than me and I trust them – they have told me to be calm, to stay in my position," said Fabregas.
"I've learned a lot tactically. I know my position on the pitch a lot more. Before I was free to do whatever on the pitch at Arsenal, and I wasn't tactically good.
"I was playing wherever I wanted, up and down. Here I have to work much more for the team, individually, and think about the team tactically."
Fabregas was part of the Catalan outfit that lost 1-0 to Chelsea on Wednesday night.
