No — there is no reliable public source currently confirming that William Saliba is left-handed.
William Saliba is a French professional footballer who plays as a center-back for Premier League club Arsenal and the France national team. Known for his strength, pace, and composure on the ball, he is considered one of the most promising young defenders in European football.
Saliba began his career at Saint-Étienne, making his professional debut in 2018. He quickly attracted attention from top clubs, leading to his transfer to Arsenal in 2019, though he spent several seasons on loan back in France at Saint-Étienne, Nice, and Marseille.
His impressive performances during his loan spells, particularly with Marseille where he was named Ligue 1 Young Player of the Year, solidified his place in Arsenal's starting lineup upon his return for the 2022-2023 season.
Saliba has also represented France at various youth levels and made his senior international debut in 2022. He has since become a key part of the national squad, contributing to their campaigns in major tournaments.
