Holger Rune stunned Novak Djokovic to win the Paris Masters title as the teenager confirmed his ascendancy into the tennis elite.
The 19-year-old defeated Djokovic 3-6 6-3 7-5, fending off the six-time champion at the indoor event to earn a place in the top 10 for the first time, becoming the first Danish man to reach such heights.
Rune becomes the first player since the ATP rankings were launched in 1973 to have beaten five top-10 players in the same tournament, other than at the season-ending ATP Finals.
His scalps on the route to his maiden Masters 1000 final included Hubert Hurkacz, Andrey Rublev, Carlos Alcaraz – who retired when trailing in their quarter-final – and Felix Auger-Aliassime.
Now Rune can add last year's Paris champion Djokovic to that list, defeating the 21-time grand slam winner who had described his young opponent as the future of tennis on the eve of the final.
Rune becomes the youngest Paris Masters champion since an 18-year-old Boris Becker triumphed in 1986, and he did it the hard way too, coming from behind after Djokovic made the stronger start.

Djokovic broke Rune's serve in the fourth game to lead 3-1 and take an early grip, soon seeing out the opening set.
Yet Rune charged 3-0 ahead in the second and grew in confidence. There was even a Djokovic-like raised fist after getting the better of his illustrious rival in one thrilling rally
Djokovic roared ahead in the decider, but not intimidated by the occasion, Rune struck back to recover the early break.
Rune then broke to lead 6-5, as his Serbian opponent became erratic.
Nobody beats Djokovic without a fight though, and the 21-time grand slam winner had six chances to break back in the next game.
Rune survived them all and clinched victory on his second match point when Djokovic, who had been chasing a record-extending 39th ATP 1000 title, netted on the half-volley.
Addressing Rune in an on-court interview, Djokovic said: "You absolutely deserve this victory. What an amazing week you had.
"I'm not happy that you beat me, but on the other hand I'm happy for you because I like your personality, I think you're a very dedicated guy that loves tennis and puts a lot of hours into hard work.
"It's paying off for you, and I'm sure the future is bright for you and your team, so congratulations."
Rune, who is working with Serena Williams' former coach Patrick Mouratoglou, said: "This must be my favourite tournament now, I really enjoyed my time here."
