Navas spoke to the team website and spoke about the reasoning behind his move to England.
“Manchester City is an exciting project and this is the right moment for me to take this step. I'm very happy with the opportunity and the decision.
“The Premier League is a competition where the football is very fast and will suit the way I play. I'm really looking forward to it.
“I'm going to a great club in England and I want to continue developing my game there. The Club has put a lot of faith in me and I want to repay them out on the pitch.”
The 27-year-old right-winger's deal is reportedly worth £17 million, including an additional £4.6 million in incentives, according to Sid Lowe of the Guardian.
While Navas only posted six assists in 37 starts for Sevilla in La Liga play this past season, that doesn't quite demonstrate his impact on the pitch. He produced 79 chances during the 2012-13 campaign, good for fifth-most in Spain. His ability to create pace and distribute the ball with precision and good timing should be welcomed at City.
Navas marks the first signing in the Manuel Pellegrini era. Interestingly enough, Pellegrini has rarely taken on natural wingers, preferring for his "wide" men to play inside, but Navas has displayed some versatility at Sevilla. This past season at the club, he was included in more central positions, given the team's lack of a high-impact playmaker.
Is this a good signing by Manchester City?
In Navas, you aren't going to get a guy with much defense and tackling ability, but in terms of offensive skills, he figures to be an asset for City as the Premier League club attempts to reclaim the EPL title from Manchester United next season.
This season, City fell short of the league title by 11 points, watching a United squad led by summer acquisition Robin van Persie score 86 goals.
City allowed the fewest goals this season in the Premier League, but ranked fifth in goals scored. In that sense, the signing of Navas makes, well, sense. City needs to boost its offensive attack after scoring 93 goals in 2011-12.
