A former Arsenal defender visited Barcelona's training ground on Thursday to observe the methods of new head coach Hansi Flick, according to a report from Barca Universal.
The unnamed former Gunners player attended the session at the Ciutat Esportiva Joan Gamper as Flick continues to implement his tactical approach ahead of the upcoming season.
Barcelona appointed Flick as head coach earlier this summer, and the German has been putting the squad through intensive tactical drills during the preseason period.
The visit highlights the interest in Flick's coaching philosophy from former professionals across Europe.
