Asked about Messi, Fabregas told Cadena COPE: I speak with Messi and his idea has always been to end his career at Barcelona.
Many things can happen at a club but I am fully confident that his career will end at Barca.
Fabregas came through Barca s youth system, leaving at 16 to join Premier League giants Arsenal in 2003.
The Spaniard established himself as one of the best midfielders in the world before returning to Barca in 2011.
Despite his strong links to Barca, Fabregas has not ruled out coaching Madrid in the future.
The 32-year-old added: You can never say never, I know this very clearly. As a player, maybe, but as a coach it is different because you can manage 30 teams in your career.
As a player the contracts are longer but as a coach you are likely to have many more opportunities because they can kick you out after two days.
