David Villa has become the first official signing of New York City FC, joining the new MLS club on a three-year deal.

"I want to try to help MLS continue to grow and try to make New York City FC become the best team in the league," Villa said.

"It's a real honor that the people who have formed the club have focused their attention on me. I'm keen to do the best I can."

Villa joined Atlético from Barcelona last season.

He has won 94 caps for Spain, scoring 56 goals, and helped them win the 2008 European Championship and the 2010 World Cup.

New York City FC head coach Jason Kreis added: "David Villa is undoubtedly one of the most accomplished and best strikers in the world."
