The German youngster is expected to taste first team football against Bradford City.
"At the moment I'm happy," Eisfeld told Arsenal Player. "I had a tough start last year because it was a big adjustment to move from German football to English football. But now everything has turned out really well and I think things can continue to progress well. But I know I can still improve.
"[My debut against Reading] was a completely unique experience and one that I will never forget. When I came onto the pitch, I had this really good feeling. I thought we could still turn the game around. Then it happened and I'm delighted that we managed to win the game in the way we did.
"I thought my performance was good, considering it was my first game, but it could have been better. I got good reviews from a lot of people and I was happy with the way it went.
"In a way it's unbelievable to make your debut in a game like that because we, the Club, wrote ourselves into the history books."
