The 21-year-old Danish central defender is looking forward to the match between the two sides and expects a good atmosphere at Oakwell.
The Tykes and Leeds will face each other at Oakwell in the Championship on Sunday afternoon.
Andersen joined Barnsley from Horsens in the summer transfer window for a fee reported by The Telegraph to be worth £900,000.
Andersen told The Yorkshire Evening Post: “I don’t know that much about Leeds. It’s a derby so there will be a lot of people coming to support us - I am really excited.
"It will be a crazy atmosphere and a good experience. We will do everything we can to win."
Leeds United are favourites
Despite Barnsley having home advantage for the Yorkshire derby, it is Leeds who will head into the Championship game as favourites.
After all, Marcelo Bielsa’s side have made the better start and also have a much better team.
While the Whites will be aiming to finish in the top two of the Championship table this season, the Reds will hope to avoid relegation to League One.
If Barnsley score an early goal, then they will have a chance, but it is hard to see anything other than a win for Leeds this weekend.
