Roberto Mancini had been tracking the former Chelsea winger for quite some time and has now finally got his man after agreeing a deal with his club Swansea
The 23-year-old winger, who played four times for Great Britain this summer at the London 2012 Olympics, has signed a deal at the Etihad Stadium and could be in line for his debut in the game against QPR on Saturday.
Sinclair moved to the Liberty Stadium in 2010 for 500,000 pounds when he impressed former manager Brendan Rodgers while on loan from Chelsea.
And after protracted negotiations looked doubtful of completion, Sinclair is relieved his move has finally gone through to join the Premier League champions.
"I'm just glad everything is settled and that I'm now a City player," said Sinclair. "There were times when I thought it might not happen so I'm relieved that I'm here and I can't wait to get started.
"Playing alongside some of the best players in the world is exciting for me and when you see two Champions League fixtures against Real Madrid on the horizon, it brings it all home."
Sinclair is Roberto Mancini's second summer signing after Jack Rodwell joined from Everton earlier this month, and could be joined by Maicon, Javi Garcia, Matija Nastasic and Richard Wright as The Blues look to strengthen their squad on the final day of the transfer window.
