Both players have been linked with moves away.
Stellini said, “I don't really deal with the transfer market, so I can't get involved with that.
“All I can say is we are very happy with Alexis Sanchez, as we are with all our players. They are all involved in the search for our objectives and it all depends on their attitude to the work, which is excellent."
Eriksen impressed in a rare full 90 minutes, replacing Marcelo Brozovic as a playmaker rather than his usual trequartista role.
“I liked his performance a great deal tonight, as he is adapting very well to this new role. It requires a lot of tactical intelligence, he is working hard all week and has done for some time, making the most of this opportunity to play great games.
“The idea was to create more space down the flanks for Perisic and Hakimi to take men on down the flank, as that's where they tend to do best.
“Eriksen is working very hard and particularly focused on the defensive movements, which he was not accustomed to thinking about. We're holding on to him tight, as he is a top level player."
