Camavinga's brother makes his debut for Lyon's U21 side, while the club adds another substitute to its squad.

In a move that will be eagerly awaited by fans of both clubs, Lyon's U21 side has announced that their star player, Camavinga, will make his debut on Saturday against Nice. The midfielder is expected to make his debut at the age of 17 years and 255 days, making him the youngest player to make his debut in Ligue 1 history.

The addition of Camavinga to Lyon's squad comes as a huge boost for the team, who have struggled to find a consistent level of form this season. The 18-year-old has been impressive in training, and it looks like he could be a key player for the rest of the season.

Meanwhile, Lyon's U21 side also made a major signing last week when they brought in a new substitute for their match against Nice. The player, who has yet to make his debut for the club, is a talented young talent who has impressed scouts with his performances for his youth team.

Overall, these two developments are significant for both clubs, and they highlight the strength of the teams involved. With Camavinga joining the squad, Lyon now have a top-class midfielder available to them, while the addition of the substitute will give the team a bit more depth in case of injury or suspension.

It remains to be seen how well Camavinga and the substitute will perform, but one thing is certain - they will be watched closely by fans and analysts alike. It should be an exciting few weeks for both teams, and we can only wait and see what happens next!
