Vink has pointed out that Kostic's actions allowed Hadj Moussa to enter the penalty area unchallenged, where he scored the goal. The ESPN-analyticus has also compared Kostic's performance to that of Zagré, who was also criticised for his defensive play in a previous match. Vink believes that Kostic's decision to let Hadj Moussa dribble past him was a crucial mistake, and that he should have been more proactive in defending.
Vink has also suggested that Kostic's role in the goal should be seen as an assist, rather than simply a defensive error. He has pointed out that Kostic's actions allowed Hadj Moussa to shoot from a more advantageous position, and that the goal was ultimately made possible by Kostic's decision to let him dribble past.
