It is claimed Dortmund want to make Wan-Bissaka their next 'English superstar' after Jadon Sancho, the winger they signed from Manchester City in 2017.
And the Crystal Palace academy product is said to be valued at £40 million, with City and Chelsea also tracking his progress.
Wan-Bissaka broke into Palace's first-team in the second half of last season, before quickly establishing himself as a regular under Roy Hodgson.
And the Eagles appear to be in a strong position to resist any offers, having tied down the 21-year-old to a new four-year contract last April.
According to the Sun, Wan-Bissaka is set to be rewarded with a first England call-up - months after his debut for the Under-21s.
Borussia Dortmund were recently credited with interest in another Crystal Palace player, Wilfried Zaha [The Guardian].
Could Dortmund, Manchester City or Chelsea prise Wan-Bissaka away from Crystal Palace?
