The German-born 18-year-old, who clinched a deadline-day loan move to Celtic from Fulham which runs until January 1, idolises the controversial Germany and Bayern Munich legend and has started putting in some research into the maverick methods which made him one of the best goalkeepers in the world.
"A lot of people say I look like Oliver Kahn and I do think his career is very remarkable," said Oberschmidt. "I have done a lot of research about him and he is a very good role model. He was very demanding of himself and of his team. I read his book and it is all about how to get on with the game off and on the pitch, about the demands of being a footballer and an athlete. Also being the manager of your own time, all that kind of stuff."
Oberschmidt was a busy man as Celtic's Under-19 side went down 2-1 to their counterparts from Barcelona at Cappielow in the inaugural Uefa Youth League on Tuesday, leaving them pointless after the first two matches of the competition which mirrors the senior team's efforts in the Champions League. But the player, who finds himself behind Fraser Forster, Lukasz Zaluska and Leonardo Fasan in the Parkhead goalkeeping hierarchy, is enjoying life in Scotland and feels games against the continent's best youth academies are productive, rather than demoralising.
"It has definitely been a good learning experience. Obviously it gets you used to the first team environment, and the things that come if you get to the first team level, like playing in front of crowds and how it affects you. I am just hoping to get myself out there, show good performances, help the club out, and get a good results. Possibly we could extend it to the summer, depending on how it goes."
Oberschmidt, who is behind the likes of Dutch No.1 Maarten Stekelenburg and England squad member David Stockdale at Craven Cottage, cut short a loan move to Ryman League outfit Harrow Borough in order to make an 11th hour switch to Parkhead.
"I played with Jack Grimmer [the former Aberdeen youngster] at Fulham - he is doing very well down there - but he didn't have to tell me too much about coming to Scotland, because I had been here before," said Oberschmidt. "I had had a one-week trial at Celtic the year before because I didn't know whether I was going to get an extension at Fulham and if that hadn't happened I would have been looking at other clubs. I was here for a week so I pretty much knew what was expected me.
"But I never expected the move. I got a call in the evening and I had to decide within about 20-30 minutes. So it was pretty quick. It was around 7.30pm and I was told the next day I had to be in Scotland . . . so I guess I had to start packing my bags! There weren't any cameras waiting for me. I managed to keep a low profile!"
Oberschmidt, who helped the London side win their Under-18 league last season, thanked Forster for the hints and tips he has passed on in training and wouldn't rule out extending his deal at the club. "I am on loan until January 1 and I think it is going quite well," he said.
