Earlier this month, reports claimed that Sanchez is unhappy at United and has instructed his agent to find him a new club.
Both Paris Saint-Germain and Real Madrid have been linked as potential destinations for Sanchez, who has failed to find his form since leaving Arsenal last January.
Asked if Sanchez could leave in January, Mourinho replied: I dont think so because he never told me that he wants to leave or isnt happy to stay.
He is improving like the team is improving, and when he plays he giving us his personality, his desire to play and to produce for the team and trying to adapt to how we play, and vice versa.
Can he do better? I think we can all do better.
I can do better and he can do better and all the other players can also do better.
