At 11, he moved to Sparta '25 in Beek en Donk, where his performances earned him attention from professional club VVV-Venlo.
Despite these setbacks, Jans regained his form and played in multiple positions, including forward, midfielder, and centre-back, helping to improve his versatility.
[1] In October 2000, Jans made his first-team debut for VVV, replacing Maurice Graef in a 1–0 home win against Eindhoven, and by the following season, he was a regular starter.
However, he struggled to maintain a consistent spot in the starting lineup, with the club frequently seeking alternatives in the forward position.
In the summer of 2010, he initially planned to join Dijkse Boys in the Topklasse,[6] but instead secured a move to Dender in Belgium.
