Thomas Tuchel has revealed his mother finds Jude Bellingham's fiery temperament on the pitch 'repulsive'.
The England manager praised the 'edge' the Real Madrid star brings to his team but admitted he must channel it towards his opponents - and not 'intimidate' team-mates.
It comes after Bellingham's meltdown following England's 3-1 defeat by Senegal, where he booted a water bottle and chased the assistant referee.
TalkSPORT put it to Tuchel that some England fans feel the Three Lions would be better off without Bellingham, to which he replied: 'I struggle to see that.
'I think it has to be the other way around, how we can have the best version of him and the best acceptance and that people understand what he's bringing to us and that he's 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 and the smile.
'If he smiles, he wins everyone, but sometimes you see the rage, the hunger 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's a special boy.
'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.
'But [channel it] towards opponents, yes, and always towards the solution, meaning towards winning. We are on that, yes. He has the fire. I don't want to dim this down. He should play with this kind of fire, that's his strength.
'But the fire comes also with some attributes that can intimidate you, maybe even as a team-mate.
You see sometimes the explosion towards referees and the anger in his game, so if he can channel this in the right way, and we can help him in this, then for sure he has the something that we need. And he has a certain edge that is hard to find.'
