Emiliano Martinez made an immediate impact at Stamford Bridge, starting just hours after his £7.5m move from Aston Villa was confirmed. Despite a shaky debut in a 4-3 victory over Brighton, the Argentina international kept a clean sheet was not primarily blamed for the concessions. Manager Xabi Alonso praised Martinez's charisma and aura, noting the goalkeeper's influence on the squad just 48 hours after his arrival. Chelsea's defense has conceded five goals in two games, but their potent attack, led by Cole Palmer, keeps them unbeaten.

By contrast, Robert Sanchez has fallen down the pecking order after errors against Fulham. Despite strong underlying stats last season, Sanchez is now available for transfer and sits fourth in goalkeeping hierarchy. Alonso emphasized the need to control matches if Chelsea are to challenge for the title, with a tough trip to Arsenal upcoming. Martinez, a two-time FIFA Best Goalkeeper, previously won the Europa League with Villa and the 2022 World Cup with Argentina. His debut signals a new era at Stamford Bridge, though defensive consistency remains the key hurdle for the Blues' title aspirations.
