Borussia Dortmund goalkeeper Roman Burki has hinted Jadon Sancho needs to suffer a playing suspension to fix his discipline problems off the pitch.

The England international, a target for Manchester United, has had several run-ins with authorities this season away from football.

Burki told BILD: "He must have no special rights. Players of his age only learn if we jointly draw a line in the sand. You can't always say he's still young. There has to be a learning curve.

"There are rules for a team and those who do not comply should receive a sporting penalty. It hits players far more than if they get a fine.

"Jadon is a special character, a good guy. Maybe one of the reasons he is so good on the field is that he is very relaxed off the field, but it is about finding the balance."
