The Blues released the England international after his contract expired at the end of the last season. The 36-year-old agreed terms to join Major League Soccer side New York City FC last month.
Lampard will now return to the Premier League on a loan spell and will play for the English champions, who are also Chelsea’s direct league rivals.
A statement on City’s official website read,” Frank Lampard has joined Manchester City ahead of his debut season with affiliate club New York City.”
“Lampard was recently unveiled as New York City FC’s fourth signing. After meetings with manager Manuel Pellegrini at City’s New York headquarters, it was decided that Frank will train and play with the Premier League champions ahead of teaming up with Jason Kreis’ New York City set-up for their inaugural season.”
After completing a move to the Etihad, Lampard said it is a fantastic opportunity to join Pellegrini’s side.
“Joining up with Manchester City is a fantastic opportunity for me to continue to train and play at the top level and make sure I am in top condition for New York City,” Lampard explained.
“It has been an amazing few days for me since the unveiling in Brooklyn and everyone connected with both clubs has been fantastic to me. This is a new chapter of my career and I’m really excited about the experience.”
“I met Manuel and some of the players in New York and I’m looking forward to getting into training and making a contribution for Manchester City ahead of my move over to New York,” the former Chelsea star concluded.
