The main event - Match no. 11: Final of the World Cup

From a logical as well as a practical viewpoint, it makes sense that the final of the inaugural WWE World Cup tournament gets to close the show. WWE more often gives the gimmick match the opportunity to end the show. Earlier this year, the Greatest Royal Rumble match ended the Greatest Royal Rumble PPV, with Braun Strowman standing tall at the end.
Moreover, the schedule of the wrestlers involved in the tournament is such that the finalists will have to be a part of three matches in a mere time interval of four hours. Hence it is only logical that their first match is in the first hour of the show, their second match comes in the middle section of the show and the final gets to close the event.
Hence, we predict that the Final match of the World Cup will be the main event of WWE Crown Jewel.
