The Brazilian has told friends he wanted a permanent move to ensure more playing time but that United only wanted to sanction a loan move at this time.
Anderson left Frankfurt on Thursday morning – having connected from Manchester – and the loan should be in place by lunchtime on Friday.
Anderson has made just four appearances for United in the Premier League this season, and eight overall.
He joined United in 2007 from Porto for around £20million, making 179 appearances and scoring nine goals.
Meanwhile, Fiorentina have injuries to Giuseppe Rossi and Mario Gomez which means they are rivalling Premier League sides for the trio of strikers being offered around on loan from Italy – Roma’s Marco Borriello and Juventus pair Mirko Vucinic and Fabio Quagliarella.
Anderson’s departure may lead to United stepping up their efforts to lure Paul Pogba back to Old Trafford.
The Frenchman, who left Manchester for Juventus in 2012, would cost in the region of £40m and has been watched in recent days by David Moyes.
Another player who could be set to leave Old Trafford is full back Fabio.
Cardiff City remain in the race to sign the defender, despite claims from his agent that he is staying at United until the summer.
