Severin Luthi worked with Roger Federer for a long time and he spoke to the media recently about Roger's decision to retire.
Luthi and Federer first started working together in 2007 and since then he's served as a coach for the Swiss player. They are very good friends and Luthi provided insight into the decision to retire in a recent interview he did.
"He just did not make enough progress. He's 41, been on the tour for so long, he's played over 1500 matches. His retirement is a combination of these factors" said Luthi adding:
"Roger makes it easy for us. Of course, it was an emotional decision for him. Otherwise, he would never have been able to achieve so much at this level. There's a lot of passion behind it. But he is always so positive about everything."
It's unclear whether Federer will play at the Laver Cup as the most recent setback makes it really hard to recover in time. According to Luthi, he'll try:
"He will try to play. Whether that's in singles or doubles, we'll see. He wants to be on the team and try to play. Roger doesn't want to put himself above the Laver Cup. But I think the reactions will be overwhelming. There will be chicken skin moments."
On Federer's favourite moments, Luthi picked:
"Spontaneously, I would say the last Wimbledon title (2017), his comeback in Australia (2017) when nobody expected him to win, the Davis Cup victory in Lille (2014), and Olympic gold in doubles with Stan Wawrinka (2008 in Beijing). And Paris (2009)"
