Hélène Hendriks thinks Theo Janssen can make a step to the Eredivisie as a trainer, according to VoetbalPrimeur. She praises Janssen's recent performances with De Treffers, who stunned Heracles Almelo 1-0 in the KNVB Beker. Hendriks is impressed by Janssen's ability to motivate his players, saying "Die spelers zijn allemaal knettergek op hem. Ze gaan door hem door het vuur."
Hendriks also commends Janssen's television analysis skills, comparing him favourably to Kenneth Perez. She believes Janssen would be successful in the Eredivisie, saying "Ik zou hem wel de kroonprins willen noemen. Hij zou het in de Eredivisie makkelijk kunnen." However, she notes that Janssen may not be willing to pursue a career in the Eredivisie, as he seems to enjoy his current lifestyle, which includes training alone in the evenings with a beer.
