The former England captain is a part of the squad, as he is playing his farewell game for the national team against the United States.
It will be Rooney's 120th cap.
And Winks is happy to get to train alongside the 33-year-old.
"I think some of the boys have probably played with him for England before but for me it is a bit surreal," he said to Sky Sports.
"When I was young, growing up you think of Wayne Rooney as England and all of the stuff he has done for his club and country it is amazing.
"To be in and around him and to train with him, you see his quality and his professionalism and he is definitely someone to learn off.
"When you are in and around someone like Wayne Rooney you have to take as much experience from him as possible.
"He has won everything, done everything and he is a top, top player - when you think of England you think of Wayne Rooney.
"To even have the opportunity to be in the camp with him and share the amazing game he has got coming up is fantastic and I am really looking forward to it."
