The Italian frontman netted in Italy Under-21s' 3-1 win over Czech Republic in the European Championships on Sunday night, but it wasn't enough to save the Azzurrini from group-stage elimination.
Rossi spent five months on loan at Parma last season, playing a major role in preserving their Serie A status and he has been linked with a switch to Juventus.
But speaking after Sunday's clash with the Czechs, the 20-year-old said: "Joining Juventus is just talk.
"I've read about it once or twice but it's not on my mind. My goal is going back to United and being able to cut it.
"My future is a bit confusing with United and I will have to evaluate the situation, but I want to play for them.
"When opportunities come along I hope to be there and impress."
