... Manchester City on loan until January, manager Manuel Pellegrini has confirmed.
The England midfielder signed for City's sister outfit New York City FC this summer, ending 13 trophy-laden years at Chelsea.
Pellegrini confirmed the 36-year-old will now move to the Etihad before the next American season begins in March.
Manuel Pellegrini: "As you know Frank has signed a contract with New York City and will start working here (the United States) in January as the season starts in March.
"From next Wednesday he will start working with our team and will play for us until then.
"At the moment he will work with the squad and be a member of the squad. He will fight for a position.
"He knows we have a very good team, we have a lot of players in his position. He is one player more.
"We have a lot of games particularly with the Champions League - so he's very important for our team."
