Emiliano Martínez takes the Chelsea No. 1 shirt after Robert Sánchez’s exit, marking a fresh start for the Argentina goalkeeper at Stamford Bridge

Emiliano Martínez has officially taken Chelsea’s No. 1 shirt following the departure of Robert Sánchez, marking a fresh chapter for the Argentina goalkeeper at Stamford Bridge.

The update was confirmed by football transfer journalist Fabrizio Romano on Friday, September 4, 2026, as Chelsea finalised the squad numbers following Sánchez’s exit.

Martínez, widely known as Dibu, now inherits one of the most prominent shirt numbers at the London club.

The No. 1 shirt is traditionally associated with a club’s first-choice goalkeeper, making the decision a notable indication of Martínez’s position within Chelsea’s squad.

The Argentine goalkeeper joined Chelsea amid significant changes to the club’s squad and will now look to establish himself as a key figure under manager Xabi Alonso.

The move also follows Sánchez’s departure, which created an opening for a new goalkeeper to take responsibility for Chelsea’s goalkeeping position.

For Martínez, the switch to No. 1 adds another layer to his new chapter in English football after establishing himself internationally as Argentina’s first-choice goalkeeper.

His reputation was significantly enhanced by his performances for Argentina, particularly during their recent major tournament successes, where his commanding presence and penalty-saving ability made him a decisive figure.

At Chelsea, Martínez will face the challenge of translating that international pedigree into consistent club performances as Alonso seeks to build a competitive side following a busy transfer window.

The announcement is therefore more than a simple squad-number change. It signals the beginning of a new goalkeeping era at Stamford Bridge following Sánchez’s exit.
