The absence of Sibisi was keenly felt as the Buccaneers struggled to maintain the same level of dominance they displayed in the first half.
The visitors managed to equalise, exposing the "imbalance" that Ouaddou alluded to following the captain's departure.
The coach admitted that while the team created enough opportunities to secure the result much earlier, the loss of defensive stability forced the game into a tense period of extra time where the players had to show significant mental fortitude to avoid an upset.
Reflecting on the impact of the injury on the pitch, Ouaddou elaborated: “I think it created some imbalance in that area; we conceded a goal.
"But what I liked it’s the braveness, character, personality of my team. We believed until the end and went until the into extra-time.
"But I think we could’ve killed the game before because Pirates really dominated that game," he concluded.
