AS Monaco forward Kylian Mbappe was sent home from training last week due to a row with teammate Andrea Raggi, according to a report.
The French teenager is one of Europe's most highly sought-after young footballers after scoring 26 goals last season at the Stade Louis II.
However, reports emerged on Saturday that the 18-year-old had been sent home from the club's base following a row with head coach Leonardo Jardim.
Now, it has been claimed by L'Equipe that Mbappe had had a bust-up with 33-year-old defender Raggi, with both players subsequently left out of the squad for Monaco's 1-0 win over Metz on Friday.
Mbappe is believed to be on the verge of a £183m move to Ligue 1 rivals Paris Saint-Germain.
