Chelsea coach has revealed how he almost lost to Tottenham in the London derby on Thursday evening. Chelsea manager Enzo Maresca has revealed that he made a big mistake that could have cost his team the win in their 1-0 victory over Tottenham Hotspur in the London derby on Thursday. Enzo Fernandez's 50th-minute header gave the blues the maximum points aganist Tottenham. What Maresca said Maresca admitted that he made a defensive change too early, bringing on defender Tosin Adarabioyo and midfielder Kiernan Dewsbury-Hall for attacker Cole Palmer and goal-scorer Enzo Fernandez. However, he soon realised that 12 minutes of stoppage time had been added, giving Tottenham ample opportunity to push for an equaliser. "When I saw 12 minutes, I saw that was probably too early to make that kind of change. But fortunately, we won the game, and we are happy," Maresca said in a post-match interview. Meanwhile, Maresca praised his team's resilience in soaking up the pressure during the extended stoppage time. "If you want to become a team, I think you need also to learn and to play in the way we played in the last 10 minutes: win a game in a dirty way," he said. Maresca also credited the return of Senegal striker Nicolas Jackson from injury, saying, "For sure, with Nico we are a different team." The win gives Chelsea a much-needed boost in their pursuit of a top-four finish and a spot in next season's Champions League.
