There he proved to be a prolific goalscorer, becoming Belgium's top scorer several consecutive seasons without any contention despite Cercle Brugge only being an average team in the league at the time.

Unfortunately he got sidelined by a serious knee injury and never got to fulfil his clearly great potential with RSC Anderlecht, one of the few glimpses he was able to show was a strong performance in the Champions League match against Hungarian team Ferencvaros.

In his international career, Weber became notable as one of the last footballers who played for national teams of two countries after being granted permission through clear connection shown from his family members.

He made his debut for Belgium on 3 June 1994 in their friendly match against Zambia, which was highly successful as he managed to score five goals in a 9–0 win.

He was also a regular member of the Belgian team at the 1994 FIFA World Cup in the United States and played in all of their four matches at the tournament, starting three of them.
