Carlos Alcaraz turned 20 recently which means he's no longer a teenager but the Spaniard would have gladly been a teenager some more to break some more records.
Alcaraz has had a spectacular start to his professional career being able to achieve many great things at a rather young age. He was even able to one-up some legendary players of the past becoming the youngest player ever to be ranked number one. It's not Nadal, it's not Djokovic and it's certainly not Federer, it's actually Carlos Alcaraz.
For that and similar reasons, the Spaniard would have liked to be a teenager for a bit longer:
"Well, I would like to be a teenager a little bit more, you know, for the stats. No, I mean, I don't feel any difference, you know, to turn 20 right now."
He then added that nothing really changed for him:
"Well, I'm just been the same person. I don't feel more adult or with more experience just for turn 20. I don't feel the difference right now."
Things in tennis did change a bit as he feels a lot more like a complete player right now compared to last year:
"I read the match better than the Carlitos last year, and I would say that's the most important thing for me, to play at the same level, to be in the same concentration all the match, and have a good physical feeling, you know. For me, that was the key and the difference from the Carlitos last year."
