Arsenal new boys Lucas Perez and Shkodran Mustafi train ahead of Southampton clash

Shkodran Mustafi looked to be settling in well to life at Arsenal following his summer transfer to the north London club as he trained with his team-mates at London Colney on Friday morning. 

Arsene Wenger’s men were put through their paces on Friday as they prepare for their home clash against Southampton on Saturday afternoon. 

Mustafi will be hoping to make his first appearance for the Gunners after signing from Valencia last month. 

Lucas Perez will also be hoping to be involved for the first time since his move from Deportivo La Coruna last week.
