Vermaelen believes Bould’s meticulous methods will help Arsenal improve this season.
“Steve is really good to work with, especially for defenders as he has been a defender himself,” the Belgian told Arsenal Player.
“He knows what it is all about and gives us a lot of tips. He works a lot on the shape of the team and that is very important, so I am very happy he came to work with the first team.
“He is very focused on details. A lot of players, because we are getting older, we know how to play. But he looks at details and the shape of your body and to be honest I am learning a lot from him.”
