Chelsea's pre-season has faced setbacks, highlighted by a 4-2 defeat to Manchester City, where defensive errors were exploited by Erling Haaland, who scored a hat-trick. New manager Enzo Maresca remains optimistic, praising attacking displays from players like Raheem Sterling, who may emerge as a key figure under his regime. Conor Gallagher is considering a move to Atletico Madrid after Chelsea indicated he would have a limited role due to Maresca's tactical approach. Maresca also noted that Enzo Fernandez is struggling with fitness after returning late from international duty, suggesting he may need to elevate his performance to secure a starting position. The coach has stressed the importance of goalkeepers in his possession-based system, indicating new signing Filip Jorgensen could play a crucial role in his tactical setup. Chelsea's focus on building a competitive squad continues as they navigate player acquisitions and fitness challenges.
