Lundgren enjoyed a successful career as both a player and coach. As a player, he won three tour-level singles titles, with his first victory coming in Cologne in 1985. He followed this up with titles in Rye Brook and San Francisco in 1987, earning him the ATP Tour’s Most Improved Player award that year. Lundgren also reached the Australian Open doubles final in 1988 alongside Jeremy Bates.

After retiring at 30, Lundgren transitioned into coaching, initially working with Marcelo Rios in 1996, helping the Chilean reach the Top 10. He then focused on junior players at the Swiss Tennis Federation before taking on a full-time role with Roger Federer from November 2000 to the end of 2003. During this period, Lundgren played a crucial role in Federer’s early success, guiding him to his first 11 tour-level titles.

Lundgren’s coaching career also included stints with other top players, such as Marat Safin, whom he coached to the 2005 Australian Open title, as well as Marcos Baghdatis, Grigor Dimitrov, and Stan Wawrinka.
