Borussia Dortmund midfielder Emre Can has slammed teammate Jadon Sancho over his haircut antics.

Former Liverpool ace Can has told Sancho to "grow up" after the England international was fined for breaking coronavirus protocols to have his hair cut.

The Manchester United target was hit with a £8,000 (€10,000) penalty by the German Football League (DFL) on Friday after being visited by celebrity barber Winnie Nana Karkari.

"We know that he just has to be more disciplined in some things, but he knows that himself," Can told Sky Deutschland.

"He just has to be smarter and grow up with things like that. He can't afford to make such mistakes in the future.

"You have to lead Jadon the right way. He's a great boy, even off the pitch. He doesn't do it on purpose to cause a scandal.

"Maybe he trusts too many other people in some things."
