Thomas Tuchel has claimed that his mother has been left "repulsed" by Jude Bellingham's vocal opposition to referees on the pitch.
The Real Madrid star kicked the ball away in annoyance at full-time of the 3-1 loss to Senegal on Tuesday, before approaching an official and kicking over a drinks cooler.
Speaking to TalkSPORT, the former Chelsea boss said: “I think it has to be the other way around, how we can have the best version of him and the best acceptance that people understand what he is bringing to us, and that he is bringing a certain edge.
“But I see that it can create mixed emotions. I see this with my parents, with my mum, that she sometimes cannot see the nice and well-educated and well-behaved guy that I see. If he smiles, he wins everyone.
“But sometimes you see the rage, you see the hunger and the rage and the fire, and it comes out in a way that can be a bit repulsive, for example, for my mother, when she sits in front of the TV.
"I see that, but in general we are very happy to have him. He is a special boy.”
While he agreed that his passion can be a good thing, he stressed that it must be channelled correctly.
“I think he has a certain something. I think he brings an edge, which we welcome and which is needed if we want to achieve big things.
“It needs to be channelled. The edge needs to be channelled toward the opponent, towards our goal and not to intimidate team-mates, or to be over aggressive to team-mates or referees."
