Question: The 2015–16 season was the 89th season in ACF Fiorentina's history and their 78th in the top-flight of Italian football, the 2015–16 season was also notable for being the first season since the 2011–12 season in which the club manager was  replaced by which former Portuguese footballer, who played as a defensive midfielder, and a current coach?
Sentence (from "2005–06 ACF Fiorentina season"): Following a successful appeal, Fiorentina was admitted to play in Serie A the following season, albeit losing its Champions League slot and having to start the season with a 15-point penalty, removing any chance of mounting a genuine title challenge and building on the success of the 2005–06 season.
Relevant evidence: No
