Head coach Ruben Amorim revealed he did not watch the penalty shootout, stating it was "not important" compared to the team's performance during the game.
Amorim accepted the fairness of the result, congratulated Grimsby, and apologised to the fans for his team's display.
He indicated a need for time to "think and decide things" about the team's future, suggesting the upcoming international break is timely.
Amorim defended goalkeeper Andre Onana, who was at fault for Grimsby's goals, by attributing the poor performance to the team's overall approach rather than individual errors.
