Henni had earlier labelled Mbappe as someone "with no values" and a person who "has completely lost it".
Now, he has come up with another round of scathing attack on the forward in a video on Instagram. He said: "He filed a complaint against me for that! For a kebab. 'Mba - complaint' Mbappe, he's turned his name into a dictatorship. Mbappe, 'Mba - round bread'. Over a kebab. Aren't you ashamed, Kylian?
"You've got nothing else to do. Mbappe attacks more in the court than on the pitch. Now I'm going to change the description and say that the bread is as round as 'his big hazelnut head'. Or bread as round 'as the Ballon d'Or you'll never get'. Kiki, you'll never win it. I'll go all the way! All the way to the trial. You say that football has changed, but it's you who has changed Kylian. It's you who's forgotten where you come from. You've forgotten your values."
