Daniel Taylor of the Guardian likely has some pretty good contacts with Manchester City as a club and with the Richards and just minutes ago he tweeted this:
Micah Richards is on his way to Italy. Loan move to Fiorentina to be made permanent next summer if all goes well. #mcfc— Daniel Taylor (@DTguardian) September 1, 2014
Taylor, rarely one for transfer gossip or fluff, would likely not have put this information out there if wasn't concrete.
It looks like the end for Richards at City and be sure to check back with Bitter and Blue for more reaction on Richards' move and the end of his Manchester City career.
