Kostic was the matchwinner in the previous week, scoring a late goal for Groningen in a match against Sparta. This came after he had been the schlemiel in the previous week, missing a crucial penalty in the Eurojackpot KNVB Beker. Voetbal International reports that Kostic's late goal was the turning point in the match, securing a 2-3 win for Groningen.
Groningen's trainer Rogier Meijer praised Kostic's performance, saying that the moment was "zeker fijn" for him. Meijer also acknowledged that Kostic's goal was a crucial one, as it helped his team to secure a win despite struggling in the first half. Meijer stated that Groningen had to work hard to overcome their opponents, but ultimately emerged victorious.
Meijer's comments suggest that Kostic's performance has been a positive development for the team, and that he is likely to continue playing a key role in their future matches.
