The German attacker has been heavily linked with a move away from the Bundesliga giants in recent weeks, with his now well-known £20m release clause due to kick in when the current season ends.
Reus has also rejected a fresh offer from BVB in a bid to keep his options open, which has prompted talk that offers in the region of £30m may be accepted by Dortmund – even though they’re aware he’s worth more.
The likes of Bayern Munich, Barcelona and Real Madrid have also been linked with the 25-year-old, but German hero Bierhoff feels there’s a good chance he may stay at the Westfalenstadion:
“I could imagine him staying at Dortmund very easily,” he is quoted by Goal.
“Dortmund are like a bank for him. Marco’s heart is at Dortmund. He knows what he’s done there and that he is appreciated.
“Marco is someone who needs a harmonious environment. But you also look at your colleagues and see who has won the DFB Pokal and the Bundesliga.
“Financially, Reus would get more anyway if he stayed at Dortmund.
“[A transfer abroad] will already be a risk but there’s also great incentive. If you’re top of Real Madrid or Barcelona’s shopping list, you wonder whether this opportunity will come again.”
