I doubt that, knowing Aulas and how much of a greedy man he is and knowing we'd flused with Pogba money, he'd ask some ridiculous fees for the 2 of them.
He isn't particularly greedy, especially if he has an agreement with his player, look at Umtiti or Benzema. The thing though is that Lyon aren't selling both Aouar and NDombélé the same year, it's not their way to do things.
