Inter players and staff reportedly had a heated altercation after last night’s defeat to Lazio.
The Nerazzurri went down 2-1 to the Biancocelesti, with Felipe Melo giving away a penalty before being shown a red card.
According to Gazzetta dello Sport, the Brazilian midfielder and captain Mauro Icardi had a verbal altercation in the dressing room after the match.
In addition, Stevan Jovetic and Roberto Mancini are believed to be become involved in an argument after the Montenegrin objected to being substituted.
The newspaper reports that Adem Ljajic, who was unhappy at not starting the game, took the side of Jovetic but urged his teammate to calm down.
Fredy Guarin, meanwhile, is said to have backed Mancini and told the former Manchester City man in no uncertain terms that he should show more respect.
It's claimed Mancini told Jovetic at half-time he'd be substituted, before changing his mind, but then withdrawing him less than 15 minutes later.
The Nerazzurri’s defeat allowed Fiorentina and Napoli to close the gap at the top to just one point, with champions Juventus a further two points back.
