Borussia Dortmund have said that they are not concerned about an Arsenal bid for Mario Gotze.

The 19-year-old is reportedly on Arsene Wenger's wish-list, with Real Madrid, Bayern Munich and Manchester United also interested.

Dortmund coach Jurgen Klopp confirmed that he does not want to sell the £30m-rated star in January.

"Nothing can happen in January. It's not a problem. Arsenal is only about 10% of what is written in Germany, so it's not a problem," said Klopp.

"Apparently, Bayern Munich are interested in him. He scored one against Bayern Munich and I will be happy if he wins against Arsenal.

"Nobody buys a player from Borussia Dortmund just like that. Not even Arsenal. Luckily, his focus is not an issue. He's very relaxed about that."

Arsenal and Dortmund meet in the Champions League tonight at the Emirates.
