"We had to set borders," managing director Michael Zorc commented, adding, "we have great confidence in him and his skills but had to take action for the team's steam's hygiene."

Zorc called Sancho a shooting-star trying to test out his boundaries, "but it is on us to show him the right way and count on professional behavior."

Dortmund's harsh reaction might be related to the cases of Ousmane Dembele and Pierre-Emerick Aubameyang back in 2017.

The French and the Gabon strikers had been a constant source of trouble when in Dortmund's shirt. Dembele forced his move to Barcelona, going on strike when he refused to return to Dortmund. He ignored a fine and his suspension.

Aubameyang followed his example only six months later, followed by his move to Premier League side Arsenal. Borussia's club leaders such as Zorc and CEO Hans-Joachim Watzke announced to accept no more blackmailing by their footballers in the future.

The English international has been in the headlines as rumors won't end speaking about him possibly leaving his current German club as early as next summer.

"You don't need to be a prophet to foresee that Jadon won't play in our shirt the next five years," Zorc commented, indicating Sancho's near possible departure. Following three goals and six assists by the English international, the former professional said Sancho at present is "one of us and willing to deliver his best."
