Aleksander Dominik Kłak (born November 24, 1970) is a retired Polish football player. Kłak was a participant at the 1992 Summer Olympics, where Poland won the silver medal. After retiring from playing due to ongoing injury problems, he became a goalkeeping coach at Royal Antwerp and a bus driver for the Antwerp public transportation network. He also battled clinical depression after retirement, and says his recovery was aided, among others, by the help of the Capucin monks and his subsequent rediscovery of his faith.
