Anderson, who enjoyed continental glory with Manchester United, is keen to help his new team improve on last season's heartache of finishing two points outside the qualification positions.
In order to qualify for Europe's elite competition, Fiorentina would need to finish third.
With the team currently sitting in fourth place, they are just three points behind third placed Napoli, and the midfielder on loan from Old Trafford thinks this target is achievable.
Speaking to Football Italia, he said: "I am very happy. I was happy at Manchester for seven or eight years, it was a big club for me and had a lot of friends, but now it's a new challenge and the time to change.
"I don't have a preferred position on the pitch. I just came here to try to help with the players, help the team and help the manager. I'll do my best.
"I saw Fiorentina lost Champions League qualification by two points last season, so this year I want to help them get into the Champions League."
