The Serie A duo join Carlo Ancelotti's side - who have been monitoring the former Paris Saint-Germain youngster for two years - as well as Borussia Dortmund, Sampdoria and Atalanta in keeping tabs on Edouard.
The France Under-21 striker said earlier this week that his focus is on Celtic, amid transfer speculation.
He said: "I actually didn't know about [the report] and it doesn't really matter. At the moment I'm a Celtic player.
"I've got a season to play, I've got a long contract, I'm really happy with the way I'm playing, the set-up here and I'm really happy to play with my friends for the team.
"The main thing at the moment is I'm a Celtic player and I'm happy to be a Celtic player.
"I've still got a lot to prove with Celtic, as part of the Celtic team. There's a long season ahead of us, we need to concentrate on that.
"The key is I've got to prove myself here first."
