According to Mossou, Weghorst had agreed with the team's fysioterapist to give a thumbs up if he was selected for Oranje and a thumbs down if not. During a training session at AZ, Weghorst's teammates were unaware of his selection status. As they trained, Weghorst's fysioterapist gave a thumbs up from the sidelines, and Weghorst immediately ran out of the training session and fell to his knees in celebration. This reaction, Mossou believes, is typical of Weghorst's emotional personality. VoetbalPrimeur reports that Mossou is a columnist and a big fan of Weghorst, who he describes as a "phenomenon" that brings a lot of colour to football.
