Saha's departure leaves the Premier League champions short of striking capability and could pave the way for the arrival of Tottenham's Dimitar Berbatov before the transfer window closes on Monday.
The arrival of the trio on the final day of the transfer window comes after the signing of FC Seoul's Ki Sung-Yong, Thomas Rogne from Stabaek, Brondby's Morten Rasmussen and Jos Hooiveld from AIK Stockholm.
