Busio, 17, is a winger and USA U17 international.
Burleson told TMW: "He's a great talent. He is a player who can play safely in Europe.
“He has great technique, he is a smart player, a box to box and he works hard. For me, if it wants to be successful at high levels, it must change soon.
“If he wants to make a great career, he has to go to Europe soon. Then the technician will decide his future, and I honestly don't think he will let him go because he is a great talent, a product of our youth sector and a player of which we are proud.
“Inter? Yes, I also know about Manchester United. These are things that came out. We also had an offer, even if not from Inter. But we didn't let him go."
