The Chilean has ditched No.17 following Tomas Rosicky’s departure from the club, joining the likes of former Gunners stars Liam Brady and Robert Pires to wear the shirt.
Arsenal unveiled their new home kit for the 2016-17 season on Monday and, with it, Alexis Sanchez picked a new shirt number.
Having donned the No.17 since arriving from Barcelona in 2014, the Chilean has taken advantage of Tomas Rosicky’s imminent departure from the Emirates Stadium by picking up the vacant No.7 shirt.
Alexis wore No.7 at Udinese but, due to David Villa and then Pedro, took up No.9 at Barcelona.
Alexis picked No.17 upon his arrival in the Premier League two years ago, with Nacho Monreal agreeing to change to No.18.
Alexis now joins a list of famous former Arsenal players to have worn the No.7 shirt, including the likes of Liam Brady, David Platt and Robert Pires.
