The Austrian narrowly fell to Tsitsipas in a third-set tie-break, with the Greek completing his transformation from Thiem’s London hitting partner three years ago to his conqueror on Sunday. Both men delivered a gripping match in what has quickly emerged as one of the most compelling rivalries on the ATP Tour.
“I'm also very sure of the fact that I can challenge him in every single match we're going to play. I really hope that we're going to have a lot of big matches coming [between] the two of us.” Thiem said of Tsitsipas.
Thiem isn’t ruling out one of those big matches taking place in a Grand Slam final. With Thiem defeating Djokovic on Tuesday and Tsitsipas eliminating Federer in Saturday’s semi-finals, they both proved once again that they can upset the Big Three when they’re playing at their best. Having faced off in last month’s Beijing final and then raised the stakes with a title match at The O2, a championship clash in a Grand Slam would be the next logical step in their rivalry.
But it’s not just Thiem and Tsitsipas who have emerged as threats to the Big Three. With half of the Top 8 comprised of players ages 26 and under, the Austrian believes it’s only a matter of time before a new Grand Slam champion emerges.
