Juventus teenager Moise Kean made history on Saturday when he became the first player born in the year 2000 to feature in a Serie A game.
The 16-year-old, who has been compared to Mario Balotelli, came on to replace Mario Mandzukic in the 84th minute with Juventus in full control of a 3-0 win over Pescara.
Kean, who was born on February 28, 2000, had previously been named to the bench five times in the league -- and twice in the Champions League -- by coach Massimiliano Allegri, but had never before made it into a game.
In September, French side Metz gave a Ligue 1 debut to Vincent Thill, who is three weeks older than Kean. Thill has already earned seven international caps for Luxembourg and even scored against Nigeria in May.
No player born in 2000 or later has yet made an appearance in the Premier League, Bundesliga or La Liga.
Juventus' win may have been straightforward, but Allegri said it was just as important to beat the minnows as it is the title contenders.
"The three points today were worth the same as the three points against Napoli or as the three points we did not get against AC Milan," Allegri told Mediaset Premium.
"Tonight it was important to win. Pescara have always made started games well and, even today, put us in trouble a couple of times, then the defence was unlocked and we won 3-0."
The champions went seven points clear at the top of Serie A ahead of Roma's game against Atalanta on Sunday, and Allegri said it was too early to say Juventus are pulling away toward a sixth straight Scudetto.
"We do not talk about escaping -- Roma must play, AC Milan as well," Allegri said.
