Johan Walem (born 1 February 1972, in Soignies, Belgium) is a former football midfielder who works as head coach of the Belgium national under-21 football team. He was considered one of the best Belgian midfielders of his generation, but gained only a few caps (36) for the national team, scoring two goals.
His former clubs are Molenbeek (as a youngster), Anderlecht, Udinese, Parma (on loan), Standard Liège, Torino and Catania. At Udinese, he was nicknamed Il Geometra (The Geometer) as he was very precise in his passes. His partnership with German striker Oliver Bierhoff was also praised at that time. After he retired he has worked as TV consultant for Belgacom TV and as youth-coach at Udinese Calcio. Walem took over the job as head coach of the Belgium national under-21 football team after the 2011-12 season.
