Chalobah's dismissal put Chelsea in a difficult position, and they struggled to recover. Brighton equalized in the 77th minute through Danny Welbeck, and Maxim De Cuyper scored the winning goal in stoppage time. Welbeck added a third goal in the final seconds of the game.
The loss marks Chelsea's second consecutive defeat in the Premier League. Last weekend, the team lost to Manchester United after goalkeeper Robert Sanchez was sent off in just four minutes. Maresca is concerned about Chelsea's lack of discipline and poor defending, which is resulting in opponents being given advantages.
According to Maresca, the team's message in the dressing room was clear: they cannot continue to give away advantages to their opponents. The red card was a significant mistake, as it changed the momentum of the game.
Chelsea had started well, taking the lead through a header from Enzo Fernandez in the 24th minute. However, Chalobah's red card led to a collapse in the team's performance. Maresca believes that the team needs to work on their discipline and defense to avoid making similar mistakes in the future.
Chelsea will face Liverpool next, and Maresca is aware of the challenge ahead. The team had control of the game initially, with 70% possession and several scoring opportunities. However, the red card changed the plan, and Chelsea struggled to recover.
