Yorbe Vertessen, a 23-year-old Belgian forward, is currently playing for Union Berlin in Germany. He has expressed his dissatisfaction with his current role as a 'joker' or super-sub at the club, despite being signed for nearly five million euros. Vertessen is determined to become a key player who starts matches and gains the coach's trust. While a return to the Jupiler Pro League in the winter is considered an option, Vertessen remains focused on making a breakthrough in Europe.
