The young German has shown significant promise at youth level with six goals and six assists in his 12 appearances for the U19s this term, prompting the Gunners to make a move for the talented starlet.
"He is a young prospect with good footballing talent," Wenger told Arsenal Player. "He has the good ingredients that could allow him to integrate into the quality of our team.
"The basics are technique, good movement and skill. We believe that he has a chance to develop well here.
"How much first-team football he has depends on him. Basically we planned to get him at the end of the season but we got him a bit earlier because he was at the end of his contract. We will use this period for adaptation."
Reflecting on his deadline day switch to north London, Eisfeld admits that the move is 'a dream come true' for him, and is confident his future will be better served at Arsenal.
"I think so because Arsenal is a great club and it is great for young players," he enthused. "The stadium is amazing, it is great.
"I am impressed with the Arsenal training centre and I really enjoy the atmosphere here. On Sunday I was at the [Aston Villa] game with my agent and it was great.
"Mr Wenger said to me that I will get the chance to train with the first team and then it is up to me if I play well."
Eisfeld could get his first taste of English football when Arsenal reserves travel to Swansea tonight, and the youngster - who becomes the latest in a series of players to swap Dortmund for north London, following in the footsteps of Tomas Rosicky and Jens Lehmann - can't wait to get going.
"It's a real honour to be teammates with the great players at Arsenal, and also training everyday with players like Tomas Rosicky - who I grew up watching play at Dortmund," he concluded.
"I will give it everything I have here and do my best to make the manager, players and fans happy."
