Manchester United have received a major boost in their pursuit of Jadon Sancho after Dortmund sporting director raised fears that they might not hold on to him for long.
The England international has picked from where he left last season, scoring three goals and providing four assists in the opening matches of the new Bundesliga season.
United are thought to be keen on the young winger, who ditched city rivals Manchester City in search of first-team action.
"No decision has been made," Zorc told Kicker when asked about his future beyond 2020.
"But you don’t have to be a prophet to know he won’t play here for another five years,"
"He has taken this positive development [at Dortmund]. I doubt that would have been possible with top English clubs. ‘We trust the players very early, and we are not afraid to let them play. He acknowledges that,"
Bundesliga giants Bayern Munich have also registered interest in Sancho, and it seems his stay at the Westfalenstadion might be a short one.
United manager Ole Gunnar Solskjaer is keen on revamping his team with young talents, having signed the likes of Aaron Wan-Bissaka and Daniel James.
