Like we said before, Lyon are continuing in the Ligue 1. They barely managed to remain. Therefore I assume they won't be able to make much of a signing this summer. You know their finances... They might even have to sell more players.
I would guess Lyon would just aim at selling as many players as they possibly can without getting relegated the old fashion way. The fact that they managed to actually stay is a big deal enough, but their finances were terrible before and now they are going to be even more debt, so I am pretty sure they will not only not get anyone, but they will also sell as many as they possibly could. Or, they could just few star players, and hope to replace them cheap, and stay in the league.
When you are doing as bad as Lyon, the aim is to just stay in the league without bankrupting, if they can do that, even if they have a horrible season, it means success. Avoiding relegation is the only goal they have and only one they should be focusing on.
