The Gabon international was announced as the club’s official new skipper earlier this month after Granit Xhaka was stripped of the armband.
Aubameyang has since been named as the new captain and he skippered the side during their 2-0 loss to Leicester City in the Premier League at the weekend.
Lacazette has now publicly backed Emery’s decision to hand Aubameyang the armband on a permanent basis.
Speaking in an interview quoted by Metro, Lacazette said: “It’s a good thing because he’s a leader on the pitch
“I think he has the capacity to be a really good captain.
“Then also he was the second in command when it came to the captaincy, so it was a natural move forward.”
The 30-year-old Aubameyang has been in fine form for Arsenal this season and has scored eight goals in 12 Premier League games for the north London side.
He has also netted once in the Europa League for Emery’s men, but his strong form has not prevented Arsenal from struggling to find results in the Premier League of late.
Arsenal have only won one of their last five games in the top flight and they currently find themselves in sixth place and eight points adrift of the top four.
The Gunners will return to Premier League action after the international break when they take on Southampton at The Emirates.
