The rationale behind Chelsea's refusal is multifaceted. Firstly, Fernandez's presence is crucial for the team as they gear up for the new season under their new manager, Enzo Maresca. Ensuring key players are available during pre-season helps in building team chemistry and integrating new tactical strategies. Missing several weeks for the Olympics would disrupt these preparations.
Secondly, there are concerns regarding Fernandez's fitness. The midfielder revealed he played through a hernia injury during the season, which ultimately required surgery in April, causing him to miss the final stretch of the campaign. Chelsea might be cautious about overloading him with international duties during his recovery and conditioning phase, which are vital for his performance in the upcoming season.
