​​Borussia Dortmund sporting director Michael Zorc has defended ​Manchester United and ​Chelsea target, Jadon Sancho, following the England international's discipline issues.

The 19-year-old was dropped by Dortmund manager Lucien Favre from the starting XI twice in recent months. He was omitted from the squad to play Borussia Monchengladbach in October because of a late arrival from England duty, and was also benched for the ​Champions League clash against ​Barcelona in November.

​Manchester United and ​Chelsea are interested in signing the out of favour Sancho in January, while ​Liverpool are rumoured to be interested too.

However, BVB sporting director Zorc has insisted there are no problems between Dortmund and the former Manchester City youngster.

"Jadon is still in the process of growing up and perfect professional behaviour, so he needs guidelines and help, and we'll give him that," Zorc told Kicker (h/t ​Mirror).

"You have no choice - you have to maintain team discipline. You have to act as a club at some point."

Zorc believes the 'punishment' had an immediate effect on Sancho who came off the bench to score against Barcelona, while also putting in a shift when the team went down to 10 men and held on to beat Hertha Berlin 2-1.

"Jadon worked brutally backwards when Mats Hummels was sent off against Berlin, " Zorc added.

Sancho scored 12 goals and provided 17 assists in his spectacular breakthrough season last term, and already has seven goals and eight assists this campaign.
