Marco Rose insists that Borussia Dortmund need more of Jude Bellingham's aggression amid claims that the England star's behaviour has upset teammates at his club.
Bellingham was caught on camera during their Europa League loss to Rangers last week lambasting Nico Schulz, telling the left-back after a heavy pass: "You can't get one f***ing pass off, you're f***ing s***. Every f***ing time."
And at half-time of Sunday's 1-1 draw with Augsburg, the 18-year-old got into a verbal altercation with experienced midfield partner Axel Wiesel in the dressing room, according Sport1.
Witsel was reportedly explaining to Bellingham, who is 15 years younger than him, on how best to press their Bundesliga opponents, although instead of taking the advice on board, the Birmingham City academy graduate is said to have waved him away.

The German outlet followed their report by claiming that Bellingham is splitting the Dortmund camp due to his attitude, adding that the highly rated midfielder is "getting on the nerves" of the club's senior players.
But manager Rose sees positives in Bellingham's overt passion, telling reporters prior to the Augsburg clash: "Where Jude comes from, you possibly speak a bit more rough in English.
"That's part of it. Jude wants to win games, he's angry - and that's part of him as a player and something we actually need even more."
Since signing from boyhood club Birmingham for £25million in 2020, the teenager has become a regular for BVB, making 80 appearances and even donning the captain's armband on numerous occasions, despite his tender age.
His form last season saw England manager Gareth Southgate call him up for the Three Lions' 26-man squad at Euro 2020.
By coming as a substitute in Southgate and co's opening game against Croatia, Bellingham briefly became the youngest player in European Championship history.
But the teenager was soon usurped to the record by Poland wonderkid and Brighton & Hove Albion prospect Kacper Kozlowski.
Bellingham has garnered recognition for his leadership skills and stayed behind on the pitch for a considerable amount of time to applaud Dortmund's travelling supporters after BVB's shock round-of-32 exit at the hands of Rangers 6-4 on aggregate, with the damage done during a humiliating 4-2 defeat at home in the first leg.
"Got what we deserved in the end after two poor performances," he posted on social media, having scored in both legs. "Can only apologise for letting the fans down again despite the unbelievable support.
"Respect and all the best to Rangers for the season. We have to start using these nights as motivation to be better, like on Sunday in the next game."
