Davide Bartesaghi, Francesco Camarda and today Jan-Carlo Simic: these are all Primavera players who made their debuts this season in Stefano Pioli's team.
The Serbian centre-back came on during the first half for his professional debut and even managed to score a goal about 20 miuntes after his entry.
This marked a record for the AC Milan team, as reported by Opta, becoming the team that fielded the most players born from January 1st, 2005, in this Serie A season: three - the others, as mentioned, being Bartesaghi and Camarda.
There was almost another 2005-born player making his debut, Alex Jimenez, who was already set to come on before Noah Okafor's injury, as per Milan News.
