Mondragon was the man behind the FC Metz’s escape from relegation from Ligue 1 at the end of the 2000–01 season. However, he was convicted of using a false Greek passport and despite the mitigating circumstances (the passport would have been provided by shysters and FC Metz had not reached the limit of players outside the EU), Mondragón was not allowed to play in France and had to leave the country. He represented Turkish power Galatasaray from 2001 to 2007, where he won two Süper Lig titles in 2002 and 2006. He was appreciated by the fans for his many saves and his commitment to the success of the team, and also become known for his prayers before and during games. He came to the fore in many European matches and was selected Player of the week in the Champions League two times. In 2011 he moved to MLS where he spent the 2011 season with Philadelphia Union being successful in providing leadership to a young team. On 30 January 2012, Deportivo Cali announced Mondragón had signed a one-year contract to finish his career with his original professional club. He retired after two and a half seasons back at the club. Mondragon made his International debut against Venezuela in 1993. He then was a member of the Colombian national teams that competed at the 1992 Summer Olympics and the 1994 and 1998 FIFA World Cup. During the 1998 World Cup, he started in goal for all three of their games, including the final match against England. Despite conceding two goals, he made some impressive saves and in doing so kept the score down to 2–0, with the BBC’s South American football correspondent Tim Vickery saying that Mondragón was “single-handedly responsible for the fact that England did not run up a cricket score”. At the end of the game, Mondragón broke down in tears and David Seaman, England’s goalkeeper, did his best to console him. According to German footballing legend Franz Beckenbauer, Mondragón had been the best goalkeeper of the first round. Along with Carlos Valderrama, the country’s most capped player, Mondragón is the only Colombian to have participated in five FIFA World Cup qualification campaigns. In 2010, he was recalled to the Colombian squad at the age of 39 after a five-year absence from international football. In 2014, he was named in Colombia’s squad for the 2014 FIFA World Cup, making him the oldest player at the tournament, and in World Cup history, at the age of 43, and the only squad member at the 1994 FIFA World Cup. He is also the only player to have participated in 6 different World Cup qualifying campaigns since 1993. By coming on as a substitute in the 85th minute of the final group game against Japan on 24 June 2014, he became the oldest player ever to play in a World Cup game at the age of 43 years and 3 days old, surpassing the record set by Roger Milla for Cameroon at the 1994 World Cup. Mondragón gave a very emotional interview afterwards, expressing his gratitude to have been given the opportunity to represent Colombia one last time at a World Cup. His record for oldest player in World Cup history was broken four years later at the 2018 World Cup by 45-year-old Egyptian goalkeeper Essam El-Hadary. After Colombia’s elimination to the host country Brazil in the quarter-finals, Mondragón officially confirmed his retirement from football and thanked the fans and nation for the support after stating, “This is my last stadium as a professional player. I’m proud to be part of this wonderful group. Thank you all for the years of support.”.
