Wenger is hoping they can recreate the success they enjoyed with Borussia Dortmund.
He said, "I hope so, yes. They are players who have played together, who know each other well and have had a successful period together. We are an offensive team and that's why I hope they can recreate that perfect understanding they had at Dortmund."
On signing Aubameyang, Wenger added: "He's a typical striker with great pace and a good ratio of games and goals scored. He has a good work rate as well and is a team player. We lost some goals because we lost Alexis, Giroud and Walcott who are all goalscorers. He will compensate on that front.
"First of all I believe that the Premier League is a challenge for every big player today. It's where everybody wants to play. Of course I've known him for a long time, he has played against Arsenal many times. He likes the way we play football and he needed a new challenge, certainly. We were the ones who could offer that to him."
