Blues finally complete Benitez deal
City faced competition from top European clubs to sign Benitez but reached agreement with the player's Mexican club in early June and now the deal has been completed.
Benitez, 23, is regarded as one of the hottest prospects in football and during the last two seasons after scoring 31 goals in 58 games.
He also featured in the 2006 World Cup and his ratio of international appearances was well above the required amount to obtain a work permit.
Benitez told the club's official website: "I am really happy to have signed for Birmingham and am looking forward to playing for the club.
"I think it is the right time for Christian Benitez to take on
the challenge of the Premier League.
"I will be giving everything to score as many goals as possible and share in good times with the club."
Benitez is the son of one of Ecuador's all time leading goalscorers, Ermen Benitez.
He made the move to Santos after previously playing for El Nacional in his home town of Quito.
