By contrast, there is a strong sporting rivalry between Mönchengladbach and the regional rival 1. FC Köln. Widely considered the most severe of Mönchengladbach's rivalries, the animosities between Mönchengladbach and Cologne had their spark in 1964, when Cologne manager Hennes Weisweiler switched allegiance in favour of Mönchengladbach. Weisweiler is a central figure in both clubs' mythologies; the mascot of Cologne is named "Hennes" in his honour, whereas Mönchengladbach venerates Weisweiler as the coach of its "team of the century". Mönchengladbach's stadium, Borussia-Park, is furthermore located at a road named "Hennes-Weisweiler-Allee" in Weisweiler's memory.
