He was announced as the new manager of Hradec Králové on 24 March 2009, replacing manager Oldřich Machala.[4] In his first full season, the 2009–10 Czech 2. Liga, Kotal led Hradec Králové to the Czech 2. Liga title and therefore promotion to the top flight. In two seasons of the Czech First League, Hradec finished in 8th and 13th place. In 2012 Kotal moved to fellow Czech First League outfit FK Jablonec.[5] He was sacked before the end of the 2012–13 season with the club lying in fifth place in the league after a 5–1 defeat against Slavia Prague.[6] Kotal returned to management in September 2013 as the new manager of FC Zbrojovka Brno.[7]
