Bacary Sagna (born 14 February 1983) is a French footballer who plays for English club Arsenal and for the France national football team. Arsenal manager Arsène Wenger has described him as the best right back in the Premier League. In addition to his regular duties in the full-back position, Sagna played for Arsenal as a centre back on several occasions.

He began his career at Auxerre, before transferring to Arsenal for £7 million in 2007. In 2014, shortly after winning the FA Cup, his first trophy at the club, he declared he will not continue in Arsenal and will move to Manchester City when contract expires on 1 July. A full international since 2007, he was selected by France for two World Cup tournaments.
