The 32-year-old joined the Nerazzurri in 2005 and was part of the team that won five Serie A titles as well as the 2010 UEFA Champions League.
But Inter completed the signing of 28-year-old keeper Samir Handanovic from Udinese earlier this month and Cesar has taken to Facebook to confirm his future lies away from the San Siro.
“These have been seven really beautiful years and plenty of them successful,” he wrote.
“But in a few days my adventure with Inter will be at an end. I thank all of you fans for the support you gave me in this time and I wish you every happiness in the future.”
With Tottenham’s first-choice keeper Brad Friedel now 41, the club have been linked with a move for France No.1 Hugo Lloris.
But Andre Villas-Boas could now turn to Cesar, a player he knows from his time on the staff at Inter.
Update: Julio Cesar told media’s that it was not his official facebook page from where they took this news!
