Dominic Thiem battled back from the verge of defeat to down world No.1 Novak Djokovic in a three-hour, three-set semi-final classic at the ATP Finals.
Roger Federer will not be losing any sleep over whether rival Rafael Nadal can match his men’s record of 20 grand slam singles titles, according to his long-term coach Severin Luthi.
The 38-year-old Swiss began the year three ahead of second-placed Nadal’s haul but the Spaniard claimed a 12th French Open title this year followed up by winning the US Open this month.
It has re-energised the GOAT (greatest of all time) debate with Nadal, who has 19 slams, looking back to his best after injury concerns earlier this year.
Never in his career has Nadal been only one grand slam title behind Federer, who squandered two match points against Novak Djokovic in this year’s Wimbledon final.
“No, I don’t think he stresses (about Nadal catching him up),” Swiss Luthi, who has toured with Federer since 2007, said.
“He focuses on himself. He has a lot of respect for Rafa and knows what it takes to win that many titles.
“I don’t see him in any way stressed. He won’t be completely destroyed if Rafa makes the 20.”
Luthi said fans of tennis should savour watching the two greats, rather than obsess about who is superior.
“It’s good for the fans. Especially the ones who thought it was all over when Roger had 16 or 17 and Rafa had 14.”
