Theo Janssen has extended his contract as head coach of De Treffers through the summer of 2031, tying his future to the Tweede Divisie club alongside technical director Jaimy Vahlkamp, who signed an indefinite agreement.
Janssen Extends Contract with De Treffers Until 2031
The extension adds two years to a deal that previously ran until 2029, a timeline noted by Voetbal International as an unexpected move given that no immediate renewal pressure existed. Janssen is currently in his second season in Groesbeek, where the amateur side sits fifth in the standings with 22 points from 12 matches.
“The ambition and sporting plan that the club expresses made me decide to extend my contract until the summer of 2031,” Janssen said through the club channels, as reported by VOETBALZONE. “I am proud and happy with the confidence from De Treffers and in particular the cooperation with Jaimy.”

Janssen outlined clear professional goals for the remainder of his tenure. “In the coming years I want to develop further as a head coach at the top of the Tweede Divisie and eventually apply for the Professional Football Coach course,” he told De Treffers.
Technical Director Vahlkamp Commits Indefinitely
Alongside the head coach, technical director Jaimy Vahlkamp converted his arrangement into a contract for an indefinite period.
“I feel very much at home at De Treffers and have been warmly welcomed by all the people within the club,” Vahlkamp told De Treffers. “The proposal to convert my contract into a contract for an indefinite period shows a lot of confidence.”
Marc Rutten, board member for football affairs, emphasized the stability the double announcement brings to the organization. “The qualities of Theo as a trainer are widely praised and the results achieved speak for themselves,” Rutten told De Treffers, adding that Vahlkamp’s continuation solidifies the club’s trajectory.
Professional Clubs and Vitesse Show Interest in Janssen
Regional newspaper De Gelderlander reported earlier that several professional clubs had approached Janssen and his management regarding potential vacancies, with preliminary discussions taking place before this extension.

Janssen also works as a technical adviser for Vitesse once a week, maintaining regular contact with technical director Bernard Schuiteman. Speaking on Ziggo Sport program Rondo, as covered by VoetbalPrimeur, Janssen addressed speculation linking him to the Arnhem club following a KNVB Beker victory over Heracles Almelo.
“If Vitesse pulls the bell, I’m going to think about it, but that’s not on the order yet,” Janssen told VoetbalPrimeur. He said that he currently lacks the mandatory UEFA Pro license required to serve independently as a head coach in professional football.
