Lyon certainly wants to immediately return to the Ligue One title competition and does not want to continue making mistakes like before. However, even so, Lyon also has to focus on bringing in other players, especially for the defender or goalkeeper positions which they feel are not very good at the moment. I miss how Lyon could be like the past where even PSG didn't have the control to stop them and I think if management uses transfer funds well then they can get the right players for the club.

Talking about Lyon it seems to make even a little change in this team and cost a lot. Lyon was a good team in the past years but recently they were not in the good form and Lyon was seen about to get relegated during this season until the half of the season when they made some changes and they finally saved Lyon from getting relegated in this season but still this won't be a good reason to say Lyon is safe and they obviously need to make the team improved for the next season.
Lyon can still make changes even though this club was in a slump last season and they also didn't recruit high-priced players. They have managed their finances so they can still recruit players. There are several players that Lyon recruited this season, such as Nemanja Matic, Said Benrahma, Malick Fafana, Orel Mangala, Lucas Perri, Adrylson and Gift Orban of course these players are not being recruited permanently, some of them are only loan options for 1 season but it is hoped that these players can strengthen their performances next season.
