Martinelli was booked by referee Anthony Taylor following the stoppage-time outburst at the injured Bradley.
The Brazilian threw the ball at the defender and tried to shove him off the pitch, despite Bradley being on the ground with an unknown injury which may grow worse after such behaviour.
Martinelli has subsequently publicly apologised, been in touch with Bradley to say sorry and also insisted that he “really didn’t understand” he was badly hurt.
Van Dijk and his teammates surrounded Bradley and confronted Martinelli in the heat of the moment as the two team’s clashed in the final moments of the game.
The towering centre back defender his team’s actions, stating that everyone came together to protect Bradley whose injury looks serious.
"Everyone was unhappy at that moment. It wasn’t a couple of players, but everyone, and rightly so because Conor was on the pitch and to be pushing him off the pitch is not really a good sight.
"It is pretty obvious for you guys to analyse it from clips. For us, it goes pretty quickly. The long ball came, Conor is challenging for it, falls down on the pitch and obviously Martinelli pushes him off the pitch and our players reacted.
"We all came together. And we had no clue what really happened, but it doesn’t look great and it doesn’t look great on Martinelli either. We are focusing on Conor now. He will have medical tests coming up in the next 24 hours and we will have to adapt."
Updates on Bradley should come from manager Arne Slot over the next week as he deals with yet another defensive injury, just a month after the defender returned to full fitness.
