Dominic Theim's former coach Gunter Bresnik is facing criticism from several tennis fans for comparing Carlos Alcaraz to the Big 3 and claiming that the latter were better than the Spaniard when they were at their peaks.In an interview with kleinezeitung.at, Bresnik was asked if Rafael Nadal would pose a threat to Carlos Alcaraz when he returns to the tour. The veteran coach agreed before adding that the reigning US Open and Wimbledon champion's level wasn't as high as the Big 3 when they were in their prime.The Tennis Letter shared a snippet of the interview on Twitter and quoted Gunter Bresnik."Gunter Bresnik, Thiem’s former coach, says Carlos Alcaraz’ level isn’t as high as Federer, Nadal, Djokovic, Murray: “I'm still convinced that Roger, Rafa, Novak & maybe Murray played better at their best than Alcaraz is doing today,” The Tennis Letter wrote.The Tennis Letter@TheTennisLetterGunter Bresnik, Thiem’s former coach, says Carlos Alcaraz’ level isn’t as high as Federer, Nadal, Djokovic, Murray:“I'm still convinced that Roger, Rafa, Novak & maybe Murray played better at their best than Alcaraz is doing today.” pic.twitter.com/0htDmFsoIx" target="_blank" title="tweet-url" rel="noopener noreferrer">pic.twitter.com/0htDmFsoIx115447Gunter Bresnik, Thiem’s former coach, says Carlos Alcaraz’ level isn’t as high as Federer, Nadal, Djokovic, Murray:“I'm still convinced that Roger, Rafa, Novak & maybe Murray played better at their best than Alcaraz is doing today.” pic.twitter.com/0htDmFsoIx" target="_blank" title="tweet-url" rel="noopener noreferrer">pic.twitter.com/0htDmFsoIxTennis fans took to Twitter to express their displeasure at the Spaniard constantly being compared to Roger Federer, Rafael Nadal, Novak Djokovic, and Andy Murray.One fan pointed out that the 20-year-old was just getting started and so should not be subjected to undue comparisons with the former champions."He is just a kid and will only get better...

Alcaraz lost the first set courtesy a shaky start, as his opponent broke his serve twice. However, he fought back and won the second set, taking the match into a decider set. Despite battling a seasoned player like Goffin, Alcaraz closed the match in his favor 4-6, 6-4, (10-8).Earlier, Belgium's Elise Mertens downed Spain's Rebeka Masarova 7-6(3), 2-6, (10-5). The Spanish duo eventually lost their mixed-doubles match to Mertens and Goffin. Against Croatia, the results were pretty similar for Spain, with Masarova losing her singles match to Donna Vekic and Alcaraz defeating Borna Coric. The Croatian pair won the mixed-doubles clash and eliminated Spain.With two successive wins after his Wimbledon triumph, Alcaraz has now registered an impressive 47-4 win-loss record in the season.
