The Argentina striker broke the news on Radio La Red.
"I have renewed the contract with Inter, so I have another two years left to run now. Then we'll have to see how I am and if I'll have the opportunity to play for Boca," said the 32-year-old.
"Years ago Julio Falconi called and wanted me to come back to Boca, but it would've been impossible. I had a contract with Genoa and I couldn't just leave."
