Tensions ran high as Inter put in their final preparations before facing off with Benfica in the Champions League quarter-final second leg on Wednesday evening.
Andre Onana and Marcelo Brozovic needed to be separated by teammates to prevent a more serious situation from breaking out.
As the Nerazzurri squad were warming up, Onana chased down a pass to Brozovic and appeared to collide with and shove the Croatian after a slightly mis-timed duel.
Brozovic did not take too kindly to the incident so soon before such an important game, but the two players were separated by teammates before the situation escalated.
