Inter began the new Serie A season with a convincing 3-0 victory over newly promoted Pescara, leaving the club's new signing optimistic over the season ahead.
Andrea Stramaccioni's side started the new campaign in fine fashion and Cassano was quick to praise the team's efforts after the game.
"The important thing was the three points. [The] performance was good, the team played well, I'm happy with this first game," Cassano told Sky Italia.
"It is easy to play with Milito and Sneijder. [They] are two high-level players, for me it's easier to play with them."
And despite the impressive performance, Cassano was quick to highlight where he and his team-mates can improve in the weeks ahead.
"We need to improve physically, if we improve physically we can improve even more at the level of play," he added.
