Lets all praise Prandelli for taking Viola to their 10th spot in Serie A, which is even worse than us.
You're willing to judge Prandelli only based on this season, can you do the same for Ranieri and Del Neri?
Prandelli has an impressive résumé:
Atalanta youth coach 1990-1997: He did a very good job developing many young players. He actually made a name of Atalanta's youth system as one of the best in Italy. It wasn't the case in the 80's before he joined them.
Lecce 1997-1998: First job as a manager where he failed and got sacked after 6 months. Lecce were demoted that season, they had even a worse second round after Prandelli's departure.
Verona 1998-2000: He led Verona back to Serie A in his first season! 9th place in his second season immediately after promotion.
Venezia 2000-2001: One season with Venezia and he led the team to Seria A, again!
Parma 2002-2004: In his first season, he led Parma to a 5th place and a UEFA cup place. In his second season, Parma maintained the 5th place and a UEFA cup place with Alberto Gilardino as a runner-up in the goal scoring charts with an impressive 23 goals.
Fiorentina 2005-now: His first season in Tuscany proved to be a huge success, as Prandelli transformed Fiorentina from relegation strugglers into a team worthy of a UEFA Champions League spot, finishing the season in fourth place. Unfortunately for Fiorentina and Prandelli however, as a result of the Calciopoli match-fixing scandal, Fiorentina along with Juventus were stripped of their Champions League spot. Prandelli's team, though, started the 2006–07 season in Serie A (albeit with a 15 point deduction) after initially being relegated to Serie B at first instance. Despite the 15 point deduction, Prandelli was able to guide Fiorentina to a 6th place finish in Serie A (with the same point tally as 5th placed Palermo), securing UEFA Cup qualification for the 2007–08 season. The team did very well in the competition, losing the penalty shootout against Rangers in the semi-final. In Serie A, the team finished fourth after winning a long race against A.C. Milan, earning a ticket to participate in the UEFA Champions League.
This season he made the 16 round of the UEFA Champions League for the first time in his Viola career (Possibly Viola's history? Not sure!).
Cesare Prandelli was twice named the winner of the Panchina D'Oro (Golden Bench) award for best Italian club coach for his work during the 2005–06 and the 2006–07 season.
For his work in the 2007–08 season, Prandelli was awarded the Serie A Coach of the Year at the "Oscar del calcio" awards in early 2009.
