The International Premier Tennis League (IPTL) has been taking Asia by storm over the past week and a half but 17-time Grand Slam champion Roger Federer has voiced some concerns over the new tournament.
"The one I think is most unnecessary here is when you start the motion and let's say you miss the ball toss, that counts as a mistake," said Federer.
The 33-year-old continued: "I'm very traditional and I like the way the game is on tour. I like the scoring system."
Crazy but fun
However, Federer also appeared to enjoy his experience, stressing that the competition is "crazy but good fun".
After electing to only participate in the Indian leg of the event, Federer made his debut for the Micromax Indian Aces franchise against the Singapore Slammers on Sunday, taking part in the men's singles against Tomas Berdych, doubles alongside Rohan Bopanna, and mixed doubles with Sania Mirza.
The Swiss ace won all three of his sets, with a 6-4 victory over Berdych, a 6-1 win against Nick Kyrgios and Lleyton Hewitt in the doubles, and a 6-0 rout of Bruno Soares and Daniela Hantuchova in the mixed doubles.
"My mind was scrambling trying to remember all the rules. It's crazy, but it's good fun."
Ana Ivanovic secured a 6-5 win over Hantuchova for the Aces, while Pat Rafter recorded a 6-2 triumph for the Singapore Slammers over Pete Sampras, in the opening set of the match.
The Indian Aces secured a dominant 26-16 victory at the New Delhi's Indira Gandhi Arena. The matches at the IPTL are decided by the number of games won, as opposed to the traditional sets format.
With all teams having played eight matches, the Indian Aces are currently top of the table with 28 points, Novak Djokovic's UAE Royals and Andy Murray's Manila Mavericks are next with 23, while the Singapore Slammers lie seven points further back at the bottom of the table.
SORRY, WHO ARE YOU?
Similar to when Maria Sharapova caused a stir after failing to recognise cricketing legend Sachin Tendulkar at Wimbledon this year, Federer likewise has outraged some Indian fans when he confessed that he was unaware of Bollywood superstar Amitabh Bachchan.
After Sharapova revealed she had not heard of Tendulkar, who watched one of her matches on Centre Court from the Royal Box, the Twitter trend #WhoIsMariaSharapova was started by angry fans.
When Federer was questioned by reporters, he admitted: "I don't know Amitabh Bachchan."
Bachchan, 72, who flew in to Delhi especially to watch the IPTL, is a veteran of almost 200 Hindi films and has a huge following across Asia, and the world. He shot to prominence in the 1970s as Bollywood's 'Angry Young Man'.
