Borussia Dortmund's hierarchy appear very concerned over Jadon Sancho's dip in form this season following Manchester United's failed pursuit of the winger.
The England international netted 17 goals and produced 16 assists last season in Bundesliga, but so far this term Sancho has failed to find the net and has only created two goals for his Dortmund team-mates.
Sancho proved to be rather ineffective as Dortmund were beaten 3-2 by Bundesliga title rivals Bayern Munich on Saturday, and after the game the club's sporting director Michael Zorc insisted something is missing from his game.
