Switzerland on 18 August 1999 won by the Czech side 3:0. In the 1990s, Petra Drnovice finished mid-table in all seasons. In 1996 and 1998 they reached the Czech Cup Final but lost to Sparta Prague and FK Jablonec respectively. In those years, Gottvald lost more and more of his influence and finally left the club after a controversy with the Chemapol CEO in 1998. Only one year later Chemapol surprisingly went bankrupt and sold Drnovice for 15 Million Czech Crowns to Persport that belonged to former tennis player Tomáš Petera. Some month later, Petera ceded the club to Jan Gottvald who became chairman of Drnovice again after five years. The 1999/2000 season saw the club reaching its best result in history when it finished third in the Czech First League. This success saw them qualify for the UEFA Cup the following season. In the preliminary round they beat FK Budućnost Banovići. In the first round they faced TSV 1860 Munich. After a goalless draw at home, Drnovice lost 1–0 in the Olympic Stadium in Munich. Financial problems highlighted those years. Gottvald had great difficulties to keep the club running. From August 2000 on, the FK Drnovice filed for bankruptcy. In a dubious transaction in March 2001 Gottvald sold the club to a widely unknown company called Corimex. In October he left the club once again. He was accused of financial fraud and other white-collar crimes and imprisoned in February 2002. The club's financial problems became so immense that it was forced to sell nine players to Marila Příbram only some weeks before the end of the season. Manager Karel Jarůšek resigned as an answer to this move. Finishing only one place short of bottom, Drnovice were to be relegated to Second Division. However, the Czech Football Association denied them the licence. In Summer 2003 Drnovice had to restart from the MSFL, the third level. In February 2003 Drnovice-based company Garimondi purchased by auction what was left of the club and ceded it to Jan Gottvald, who once again took charge of the club after being set free on a 20 Million Czech crowns bail. Gottvald strengthened the squad, Drnovice won the MSFL without any problems. They finished as runner-up in the 2003/2004 season in Second Division and were promoted to the Czech First League. In the summer of 2004, Swiss-based company Sunstone acquired the club, that finished in 8th
