An old comment from Nick Kyrgios became a talking point on social media after Pablo Carreno Busta sealed his maiden ATP Masters 1000 title at the 2022 Canadian Open on Sunday. Carreno Busta stunned 8th seed Hubert Hurkacz to register a 3-6, 6-3, 6-3 win and clinch the hardcourt Masters title.A couple of years ago, Kyrgios had suggested that Carreno Busta was just a clay specialist and said that the former Top 10 player wouldn't even be close to the Top 50 in the ATP rankings without claycourt tournaments. The comment caused a rift between the two players that is still ongoing.We Are Tennis@WeAreTennis📸 Nick Kyrgios, about Pablo Carreño Busta, September 2020.Carreño Busta on hard courts, now M1000 : 1 Slam semis: 2Kyrgios on hard courts, now M1000 : 0 Slam semis: 0Karma 1100108📸 Nick Kyrgios, about Pablo Carreño Busta, September 2020.Carreño Busta on hard courts, now M1000 🏆: 1 Slam semis: 2Kyrgios on hard courts, now M1000 🏆: 0 Slam semis: 0Karma 😬 https://t.co/jxRGi6e1cZCarreno Busta won this year's Canadian Open title after winning a bronze medal at last year's Tokyo Olympics, which were also played on hardcourts. The Spaniard defeated Novak Djokovic in the Olympic bronze medal match.Tennis fans recalled Kyrgios' old dig after the Spaniard won his biggest ATP title to date. One fan said that, on similar lines, Kyrgios himself would never have been successful if tennis was played only on claycourts, given the Australian player's record on the surface."If only clay existed, no one would have ever heard of Kyrgios," said a post on Twitter.Sean@SeaninCT@WeAreTennis If only clay existed, no one would have ever heard of Kyrgios.24@WeAreTennis If only clay existed, no one would have ever heard of Kyrgios.GJD@GazJD7@WeAreTennis I'm pretty sure he said this about Casper Ruud and not PCB.
