Spain's Carlos Alcaraz and Italy's Jannik Sinner have produced many mouthwatering clashes already, cementing their place as one of the most interesting rivalries to look forward to in the years to come. The pair's matches have all had neck-to-neck scorelines, leaving fans wondering until the last minute who will emerge victorious.Before the 2023 BNP Paribas Open, the young players were tied 2-2 in their head-to-head, which has now turned 3-2 in favor of the Spaniard. Meeting in the semifinals in Indian Wells, Alcaraz prevailed 7-6(4), 6-3 in straight sets to book his place in the summit clash.The pair last met at last year's US Open in the quarterfinals, where Alcaraz overcame Sinner in five sets in a match that lasted over five hours. Sinner, meanwhile, outclassed Alcaraz at Wimbledon last year in a four-set match in the Round of 16. Apart from the quality of tennis produced, the pair also share mutual respect for each other, drawing comparisons to the legendary Rafael Nadal and Roger Federer -- who, besides being fierce competitors on the court, were great friends off it as well.Tennis fans on Twitter almost unanimously agreed that 21-year-old Sinner and 19-year-old Alcaraz are capable of stitching together a rivalry to watch out for after watching their blockbuster Indian Wells clash."Is it a hot take to say that Alcaraz-Sinner is the best rivalry in the ATP right now?"
