The Serie A giants parted ways with the Danish midfielder last week after it was revealed he is not allowed to play in Italy with a implantable cardio defibrillator.
The ICD was fitted to the player after he suffered a cardiac arrest in Denmark's opening game of the European Championship in June.
"It's too early to say where Christian's future lies," Schoots told Sky Sports.
"Because of special regulations in Italy, which have already existed for decades, the only thing we know for sure is that it will not be in Italy. And it will not be in another continent either, because of family reasons.
"A few clubs have already contacted us some weeks ago. We have to see what the future brings. But it seems bright and that is the most important thing."
