Stefanos Tsitsipas and Dominic Thiem have both donned regulation grey Adidas shirts this week but their techni-color games will light up the O2 Arena in the ATP Finals climax today.
Appropriately, the two standout performers will meet after 21-year-old Greek debutant Tsitsipas eclipsed six-times champion Roger Federer 6-3, 6-4 and Austrian Thiem dispatched defending champion Alexander Zverev 7-5, 6-3.
It will be only the third time since 2002 that at least one of Federer, Nadal or Djokovic have not reached the final and the week has felt like a momentum shift for the new generation.
While Thiem qualified for the last three years while Tsitsipas has wowed the London crowds for the first time with his fearless attacking style.
