Manchester United midfielder Anderson has posted a note to the club's fans on Instagram, thanking them for their support ahead of his move to Fiorentina.
The Brazilian midfielder underwent a medical today – and is expected to finalise his transfer at the start of next week, once a work permit has been granted.
The 25-year-old posted a heartfelt message to supporters of the Premier League champions, before promising to give his all for his new employers.
"Thank you Manchester United for all you gave to me," Anderson wrote. "It was a pleasure and a proud to be part of this tremendous club. I will never forget my great colleagues and friends, all the amazing people that work in the club and obviously the fantastic supporters, always on my side.
"Love you all and you always be in my heart. Wish you all the best because we always be together United family!"
"Now I have to leave because I really need to play. Thank you Fiorentina for this opportunity and you believe in me. You won't regret because you trust me 100% and I will give you 100% of dedication, professionalism and quality. Together we will be happy."
Anderson arrived at Old Trafford from FC Porto in 2007 but failed to establish himself as a first-team regular during his six-and-a-half years with the reigning Premier League champions.
With the 2014 World Cup finals just around the corner, Anderson has little time to force his way back into the Brazil side.
However, a run in the Fiorentina team between now and the summer could give Brazil coach Luiz Felipe Scolari something to think about.
