It broke yesterday that the Uruguay defender was willing to listen to offers about leaving this summer, despite penning a new deal only earlier in the year.
But Flick said this morning: "There are always a lot of rumors about Araújo, but I haven't heard anything or any indication that he wants to leave. I have a great team, with a lot of quality.
"We have doubled all the positions and in some I even have three players. It's not easy to manage, of course, but I'm happy (…) I'm surprised this is coming out of Ronald. I'm very happy with the team I have."
Flick also had a word for new signing Marcus Rashford, adding: "Marcus is a great player. I've followed him for many years, since he began his career at United. He has a lot of quality, and we hope he can show it in the team."
