Sancho, 20, is keen to quit the German side for a big move, with Man United leading the race.
According to SPORT BILD though, no final decision will be made until August at the very earliest.
Dortmund believe they are in a strong position considering Sancho is under contract until 2022.
If a club offered €130m for the young superstar, then BVB would reluctantly sell him – but will anyone pay that?
Only Manchester United are in the running as things stand and have yet to formulate a bid to repatriate Sancho.
And hope is rising in Dortmund that Sancho could remain at the Westfalenstadion.
The Bundesliga giants are considering a major wage increase to convince the England international to stay another year.
Sancho currently makes €6m-per-season but could earn up to €10m if he accepts BVB’s proposed deal.
Considered one of the world’s most talented youngsters, Sancho has amassed an incredible 17 goals and 16 assists in the Bundesliga this season.
