Kenneth Perez, a well-known analyst, has spoken out about Etienne Vaessen's recent behaviour. According to Perez, Vaessen has difficulty controlling his emotions, which makes him unsuitable for a top club. In an interview, Perez stated that Vaessen is a good goalkeeper for FC Groningen's level, but that's as far as it goes. He believes that Vaessen's sensitivity and emotional struggles are key factors in his inability to play at a higher level. Maarten Wijffels, a journalist for the Algemeen Dagblad, also agrees that Vaessen is not suited for a higher level.
