According to the Italian media at that time, AC Milan had hoped to use Sissoko's dental issues as a reason to reduce the price by 4 million euros. Unexpectedly, Porto showed no intention of compromising. As a result, this deal became a laughingstock. After missing out on AC Milan, Sissoko joined Lyon for 15 million euros. Upon returning to Ligue 1, he quickly proved his talent. To date, Sissoko has played a total of 4971 minutes in 57 appearances for Lyon. This player who was once rejected by AC Milan has become an ace in Ligue 1. On November 5, 2009, Sissoko was also selected for the French national team. Before the start of the South Africa World Cup, he was also included in the list of 30 players. He made his debut in August. On October 23, *France Football* reported that AC Milan intended to sign Lyon winger Sissoko. Notably, in 2009, AC Milan had officially announced on their club website that they had completed the transfer of Sissoko. Unexpectedly, later AC Milan returned him, citing dental issues as the reason. Clearly, Sissoko's outstanding performance in Ligue 1 has once again drawn the attention of AC Milan. *France Football* believes that the Rossoneri are targeting Sissoko again to address the problems in their left-back position. Currently, Sissoko's contract with Lyon will expire in 2014. *France Football* estimates that Sissoko's value is as high as 15 million euros. Regardless of whether AC Milan might still consider Sissoko's price too high, Sissoko, who once suffered humiliation, must certainly have mixed feelings about the olive branch extended by the Rossoneri. In the summer of 2009, after Maldini retired and Kaka was sold, AC Milan prepared to sign a new full-back. On June 14 local time, AC Milan's official website announced that Sissoko would join the club. According to the agreement between the two clubs, Sissoko's transfer fee was 15 million euros plus an additional 1 million euro clause. Unexpectedly, just as the deal was about to be finalized, AC Milan discovered an issue with Sissoko's teeth. Later, due to unsuccessful negotiations between the two clubs, this deal that was almost done fell through. Regarding the reason for the failed transfer, Sissoko believed, "There was nothing wrong with my teeth; the two clubs had disagreements over the transfer fee at the last moment."
