Iraola believed the referee's performance was significantly influenced by the game's early stages, particularly the penalty decision. He stated that the referee lost control of the game, starting with the penalty call.

Iraola also pointed out other questionable referee decisions, including a foul that led to the third goal and a red card discussion in a previous match. He acknowledged the importance of self-reflection, particularly in defensive set plays, which have been a recurring issue for the team.

However, Iraola emphasized that the referee's influence was significant, saying, "The referee has been very influential, very, very influential."

The loss to Sunderland marked a disappointing end to the match for Bournemouth, and Iraola's comments reflect his frustration with the team's performance and the referee's decisions.
