French club Lyon has signed a new defender for their U21 team ahead of the January transfer window. The player, who is yet to be named, will join the squad at the beginning of the month and will be expected to make an immediate impact.

The signing of this new defender comes as part of Lyon's efforts to strengthen their squad ahead of the upcoming season. With several key players set to leave the club during the transfer window, Lyon will need to bring in reinforcements to ensure that they remain competitive in the league and in European competitions.

The player, who has been impressive at his previous club, is likely to have impressed Lyon's coaching staff with his skills and experience. He may well be a young talent who could develop into a key player for the club in the future, or he could be someone who can step up immediately and help the team achieve their goals.

Regardless of his position, the addition of this new defender to Lyon's squad will undoubtedly add depth and strength to their defensive line. With the likes of Marquinhos, Evra, and Kounde already established at the club, the arrival of this new defender will provide another option for the coach to choose from when selecting his starting XI.

Overall, the signing of this new defender by Lyon is a positive move for the club and its fans. It shows that the club is committed to improving their squad and ensuring that they remain one of the top teams in France and Europe.
