Theo Janssen is making a lot of impression on his players and former colleagues as a trainer of De Treffers. The amateur club is currently second in the Tweede Divisie and will face Heracles Almelo in the KNVB Beker on Thursday. Edward Sturing believes that Janssen has all the qualities to work in professional football. Janssen has extended his contract with De Treffers for three years and is in the midst of a successful period with the club. Sturing, who knows Janssen from his time at Vitesse, thinks that Janssen has a bright future as a trainer in professional football. "Theo speaks the language of the players," Sturing told the Algemeen Dagblad. De Treffers' goalkeeper Joey Kesting praises Janssen's calm and effective coaching style, saying that he knows exactly how to motivate his players. Team captain Steven van der Heijden is impressed by Janssen's tactical insight and ability to communicate effectively with his players.
