17-YEAR-OLD Jadon Sancho is already asserting his authority within the Borussia Dortmund camp.
The England youngster had last term's top scorer Pierre-Emerick Aubameyang cleaning his boots for him after a training session.
Sancho filmed his team-mate in the act and uploaded it to - which has 135,000 followers.
Aubameyang appeared in high spirits as the pair were in hysteric's as the striker scrubbed the Nike boots in the sink.
Dortmund are top of the Bundesliga standings, with talisman Aubameyang already tallying 11 goals and one assist.
The in-demand wonderkid was called back from the England Under-17 set up to join Borussia Dortmund's senior squad last week.
He made history when he was introduced as a late substitute during BVB's enthralling 2-2 draw Eintracht Frankfurt.
Sancho became the first-ever Englishman to represent the German giants following his £8million switch from Manchester City.
The teenage prospect came close to snatching a late winner for Peter Bosz's side, but his effort was saved in the dying moments.
His emphatic form the Three Lions led to Dortmund handing him the No.7 shirt that was previously held by Ousmane Demebele.
Sancho has been a key star throughout England Under 17's World Cup campaign - scoring three goals to help them qualify for the last 16.
Sources in Madrid confirmed that Real Madrid sent scouts to watch the wonderkid on his BVB debut.
The Spanish giants have indicated their interest in the youngster and are monitoring his progress.
