Former Gunner Lehmann is back at London Colney once again, working with outfield players and goalkeepers as Arsenal continue their pre-season training.
The German keeper oversaw a session involving Sead Kolasinac, Mesut Ozil and Danny Welbeck as Arsene Wenger’s squad get back up to speed ahead of the new season.
