Diego Costa has once again publicly attacked Antonio Conte, reigniting a rivalry that dates back to their years together at Chelsea. A guest on John Obi Mikel's podcast, the former London Blues midfielder—the Spanish-Brazilian striker, now a free agent—painted a severe portrayal of the Italian manager, who is currently in charge of Napoli, one of the historic teams in Serie A. Costa distinguishes between Conte the strategist and Conte the man: while he appreciates his tactical worth, his opinion on the personal level is straight-forward. He characterized Conte as a perpetually in a bad mood, convinced that he is always right, and a constantly in a bad mood. He even made a deliberately provocative joke about his private life to explain his bitterness, stating, "Maybe he is such a bitter person because he doesn't have sex at home". According to Costa, the anxiety was not only personal, but also prevalent in Chelsea's dressing room, one of the most popular teams in the English Premier League. Training under Conte, he claims, was unpleasant, and while many teammates advocated for his return to the club, few had genuine regard for the coach. This climate, according to the striker, contributed to Conte's brief stay in London, despite his sporting achievements. To comprehend the scope of the conflict, we must go back to 2017. Following his victory in the Premier League, the premier English league, Conte decided to exclude Costa from his future plans. He conveyed this decision through a straightforward text message, rather than in person. This gesture was seen disrespectful in the context of top-tier European soccer, particularly towards a striker who had played a significant role in the title's success. A lengthy contract struggle occurred, culminating in Costa's return to Atlético Madrid in Spain.
