It was during a match between the teams in August last year that the controversial banner was seen among the home crowd at Selhurst Park.
The banner depicted Marinakis pointing a gun at Nottingham player Morgan Gibbs-White. According to the BBC, Nottingham owner Evangelos Marinakis is now suing Crystal Palace for defamation.
Last summer, Gibbs-White was close to a move to Tottenham, but Nottingham pulled out of the deal.
The banner also featured a speech bubble from the player's mouth with the text:
"Mr. Marinakis is not involved in extortion, match-fixing, drug trafficking or corruption." These are allegations that Marinakis has previously denied.
