Monaco starlet Kylian Mbappe was reportedly involved in a training-ground scrap with Italian defender Andrea Raggi last week.
According to L’Equipe, Mbappe fought with Raggi last Tuesday, resulting in his expulsion from training.
However, the 18-year-old refused to go back into the changing rooms, forcing his teammates to move to another pitch.
Mbappe was not in the French champions’ squad for their 1-0 win at Metz last Friday, amidst speculation that he is close to joining Paris Saint-Germain for another nine-figure sum.
Raggi, meanwhile, has been at Monaco since being signed by Claudio Ranieri 2012, helping the team return to Ligue 1 in his first season and subsequently lift the top-flight title last term.
