In December 2013 Tan bought Bosnian club FK Sarajevo. Under the deal, Cardiff will cooperate with FK Sarajevo, exchanging players and taking part in a football academy, yet to be established, which Tan has said will lure new talents. FK Sarajevo have since brought in players such as Miloš Stojčev, Džemal Berberović and Nemanja Bilbija, who helped the club win the 2013–14 Bosnian Cup, their first title since winning the domestic Premier League in 2006–07. Prior to the Cup triumph, Robert Jarni was brought in as manager of the club in December 2013 by Tan, but was dismissed after only four months (on 7 April 2014, while the team were still in the semi-finals of the Bosnian Cup) because the club had failed to keep their chances of winning the premier league title alive during the later stages of the 2013-14 season. In July 2014 FK Sarajevo played a friendly match against Tan's Cardiff City FC U21, winning 4–1. FK Sarajevo qualified for the Play-off round of the 2014–15 UEFA Europa League, where they lost to German Bundesliga side Borussia Mönchengladbach.
