The Argentine has completed his move from City to the Italian champions and suggests that the Turin outfit are more intent on winning the Champions League than his former club.
"Four years ago, I chose to move to City because of the targets they were aiming for," he said.
"I wanted to play in the Champions League and help the team win a league title after a long gap. I've noted the same ambitions at Juventus.
"They want to keep finishing first in Italy, as they've done over the past two years, and aspire to win the Champions League. This made my decision easier."
