Severin Luthi has long been one of Roger Federer's closest men, as well as his first fan. He has toured with Federer since 2007. He coached the team that won the Davis Cup for Switzerland in November 2014, as Roger Federer beat Richard Gasquet.
Tennis Channel recently invited four-time Major winner Jim Courier and the legendary Martina Navratilova to discuss Roger Federer's relationship with Severin Luthi.
Navratilova on Roger Federer and Severin Luthi
"What I like about Roger Federer, according to what Severin Luthi told me, he does not validate himself based on winning or losing.
He's still the same guy, you know. And people lose sight of that, but Roger never has," Martina Navratilova said. The reason Federer and Luthi have bucked that trend, according to Navratilova, is the honesty in their relationship.
"Most of the time people say yes because they don't want to be fired, but the player needs honesty," Navratilova said. "And this is why I think the relationship between Roger Federer and Severin Luthi has lasted so long.
Amazing how the two have lasted at a time where players are changing their coaches all the time. They're probably symbiotic. Severin has said he's learnt some things from Roger, of course Roger has learnt a lot of things from him.
They kind of play off of each other," Navratilova added. In his most prolific year, in 2006, Federer won 92 matches. Since 2001 there have been only two years when he has won fewer than 50 matches. In 2013, when he won only one title, he won 45 matches, and in 2016, when he took off the last six months of the year because of a knee injury, he won only 21.
He needs 33 more victories to overhaul Jimmy Connors’ Open era record. Upon winning the 2009 French Open and completing the career Grand Slam, Federer became the first individual male tennis player to grace the cover of Sports Illustrated since Andre Agassi in 1999.
He was also the first non-American player to appear on the cover of the magazine since Stefan Edberg in 1992. Federer again made the cover of Sports Illustrated following his record-breaking 8th Wimbledon title and second Grand Slam of 2017, becoming the first male tennis player to be featured on the cover since himself in 2009.
Federer helped to lead a revival in tennis known by many as the Golden Age. This led to increased interest in the sport, which in turn led to higher revenues for many venues across tennis.
