Despite the constant hair-touching against Udinese, and perhaps because he got his hair cut the following day, Juve's new No.15 came off the bench again the following weekend, this time in a 1-1 draw with Bologna in Turin.
Three further Serie A appearances followed by the end of October and, on November 7, Yildiz was officially promoted to the first team, with Allegri declaring, "Kenan will become a great player."
However, it wouldn't be long before more reports of unrest appeared in the press. After making his Turkey debut as a substitute in the Euro 2024 qualifying win over Croatia on October 12, Yildiz was selected to start in a friendly against Germany the following month, and netted his first international goal against the country of his birth. He featured again three days later, coming off the bench to win the penalty with which Yusuf Yazici earned Turkey a crucial 1-1 draw with Wales in Cardiff.
According to reports, Yildiz and his representatives felt that his exploits with his national team proved that he deserved even more game time at club level. With very little forthcoming, talk of a transfer intensified as the January window approached, with Arsenal, Liverpool, Fenerbahce, Galatasaray and Benfica all credited with interest.
However, Allegri brought Yildiz on late in a 1-1 draw at Genoa on December 15 - his first Serie A appearance since October - before starting him against Frosinone eight days later. With Yildiz once again determined to impress, he took just 12 minutes to open his Juve account with a stunning individual goal, thus becoming the youngest foreign player ever to score for the club.
"For me, this is too great," a visibly emotional Yildiz told DAZN after the 2-1 win at the Stadio Benito Stirpe. "Thanks to everyone. To the fans, they are crazy, look at them! And thanks to the coach who gave me a chance. The mister is a great coach for me. When he told me to cut my hair, I didn't wait, and I did what he said. He told me to be calm and he gave me my chance today!"
