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.
I'm not sure if selling all the players is the best option, given Lyon's massive debt and the ongoing sanctions. I can't imagine how the team will fare in Ligue 1 with only the players they have. It's incredibly painful, and the situation is truly extremely difficult, with no solution available unless a major investor steps in to rescue Lyon. For now, management is working to keep Lyon afloat, and hopefully, there's still another option other than selling their best players.
