With Mario Gotze set to leave the Westfalenstadion for Bayern Munich in the summer, the Bundesliga giants are said to be targeting the Dane to replace him.
And while Eriksen admits that he could move on from the Amsterdam ArenA this summer, having heard of interest from BVB.
"I've read that," the 21-year-old told AD about reports linking him with the German club. "It's great that [the media] link me with such a good club. But right now I'm only focusing on one thing. I want to become a champion and after that we'll see.
"If nothing happens, I'll renew my contract. I owe Ajax so much. I don't want to leave for free."
Ajax is edging closer to winning the Eredivisie title where it sits top of the table, four points clear of PSV.
