“The situation is currently unbearable and I will not come back to the national team,” Stoychev declared on Wednesday.
Stoychev was controversially dismissed Sunday, a day after the heavy favorites for the 2012 Olympic Games-European Qualification Tournament were defeated by Germany in the second semifinal.
The general public and several key national team players have criticized the Bulgarian Volleyball Federation for its decision to fire Stoychev, who learned about his own dismissal from the media. Star Matey Kaziyski said he considered quitting the team.
On Tuesday, Italian Silvano Prandi declined the invitation to become head coach of the national team, explaining that he does not believe the federation can cooperate with him in a proper manner.
