"Job finished - 4/4 complete."
That was the message Carlos Alcaraz wrote on a TV camera lens after creating history with his Australian Open final victory over Novak Djokovic on Sunday.
Aged 22 years and 272 days, Alcaraz is the youngest man to complete the career Grand Slam, and only the ninth male player in history to win the singles title at all four tennis majors.
With fellow Spaniard and 22-time major champion Rafael Nadal watching from the stands on Rod Laver Arena, Alcaraz collapsed to the floor in a mixture of tiredness and jubilation as Djokovic's long forehand on match point sealed a 2-6 6-2 6-3 7-5 win.
Alcaraz has tattoos to commemorate his previous Grand Slam wins. He said he will try to "choose a good spot" for the planned kangaroo tattoo that will mark his maiden victory in Melbourne.
He went on to say that fulfilling the busy tennis calendar can leave little time to "stop yourself and think about what you're doing" - but the world number one is determined to make sure this latest success sinks in.
"What I've learned this year is about appreciating and enjoying every single second - not only lifting trophies but playing tournaments, playing tennis, getting victories, getting losses," said Alcaraz.
"Whatever it is, just enjoy and appreciate the life you're living.
"It's an honour to put my name on the history books."
