Eisfeld joined the Gunners from Borussia Dortmund on Tuesday, following in the footsteps of the man he idolised as a youngster.
Rosicky cost Dortmund 14.5million euros when he joined the Bundesliga club from Sparta Prague in 2001 and earned the nickname 'the Little Mozart' due to his composure and style.
The 19-year-old attacking midfielder, who could make his debut for the reserves in Wednesday night's game at Swansea, told Arsenal TV Online: "My hero was Tomas Rosicky. I have a shot of him in my room and it's fantastic to play with him."
Eisfeld revealed he used to watch Rosicky play while he was coming through the ranks at Dortmund.
He added: "In my opinion, he's a great player and I focus on his game. But I play a little bit differently. I think I can read the game very well and my technique is quite good."
Eisfeld also trained alongside Thierry Henry on Tuesday.
"I feel proud because to train with players like Thierry Henry is a dream of each player," he said. "It's like a dream come true for me."
Eisfeld did not play for the Dortmund first team but scored six goals and created another six in 12 appearances for their under-19s this season.
He had no fears about joining Arsenal, citing manager Arsene Wenger's record at nurturing youngsters.
"The trainer is great for young players," he said.
"Mr Wenger said to me that I will get the chance to train with the first team and then it's up to me if I play or I don't play."
