Borussia Dortmund 'are working with the same agent who masterminded their mega-money sales of Ousmane Dembele and Pierre-Emerick Aubameyang' in negotiations with Manchester United over Jadon Sancho.
It comes as United threaten to walk away from the deal if Dortmund, who are demanding £108million for the 20-year-old England winger, don't compromise with their asking price.
The Old Trafford club believes Dortmund are being unrealistic in their demands for Sancho given the current economic climate amid the Covid-19 pandemic.
But Dortmund are determined one of their star assets won't be sold below their valuation and, according to German newspaper Bild, have enlisted the help of a man used in the Dembele and Aubameyang deals.
