The 27-year-old signing from Sevilla linked up with his new team-mates for the Asia Trophy in Hong Kong, and believes his new manager's "clear vision" will be crucial
The 27-year-old, one of a number of major coups by City this summer, joined up with the squad for their Barclays Asia Trophy in Hong Kong this week.
And as he looks forward to the impending season, Navas was full of praise for his new manager.
“Manuel [Pellegrini] is a great coach. He has clear ideas and a clear vision, and he will get the best out of all of us,” Navas told the club's official website.
“I’m very happy to be here and I think we can enjoy [the Premier League] a lot this season.
“It is important to get fit for the start of the season. As I said, I’m very happy here and I’m sure we will do big things this season.”
City won the tournament in Hong Kong on a boggy pitch against Sunderland 1-0, with Edin Dzeko scoring the winning goal.
And Navas said he was pleased with the welcome he has received since arriving at the club from Sevilla.
“My team-mates were extremely friendly to me and it’s important to have this feeling,” added Navas.
“It was really important [settling in here in Hong Kong]. The Premier League starts in a few weeks so it is important to get fit and ready for the action.
“We’re happy to win this title, but the most important thing is to get fit for the Premier League.
“I have never been [to Manchester] but I have been told it rains a lot, but it also rained a lot this week in Hong Kong so I will be fine with the weather.”
