Lyon FC has announced the signing of a new French U-21 defender, making it their fifth signing this winter.

The 21-year-old defender, who previously played for Paris Saint-Germain, has joined Lyon from Nice FC in order to bolster their defensive system ahead of the January transfer window.

The signing marks another step in the club's evolution as they look to improve their squad and compete for the La Liga title next season.

The defender, known for his physicality and ability to handle both attacking and defensive challenges, will provide additional depth to Lyon's defense, which currently stands at just three defenders.

In addition to his playing time, he will also bring valuable experience to the team, as he has spent several years with Nice FC and has been involved in many key matches during that time.

The move is seen as a positive development for Lyon FC, who have struggled to maintain their form this season and need to strengthen their defensive system if they want to compete for the top leagues in Europe.

It remains to be seen how well the defender will perform on the pitch for Lyon, but his signing should help them build a stronger defensive line and improve their chances of success in the upcoming campaign.
